The Old Greek translation was the version originally in the Septuagint, however, the authenticity and accuracy of any and all versions of the Book of Daniel have always been in doubt. The Codex Chisianus (also known as the Chigi Manuscript 88) is accepted as being the closest to the Old Greek translation. It claims to be a copy of the Christian scholar Origen of Alexandria's recension from circa 240 AD, and as the Syriac translation of Origen's recension from 616 and 617 AD, the Syro-Hexaplar Codex, is virtually identical, they are both accepted as Origen's work. Origen rejected both the shorter version of Daniel found in the Hebrew and Aramaic translation that the Jews of his day were using, as well as Theodotion's translation, which was largely based on the Hebrew and Aramaic text, and claimed the Old Greek translation was the closest to the original text of Daniel. In 1931, a damaged papyrus from the 3rd-century AD was found, now known as Papyrus 967, which contains a Greek translation of Daniel that is similar to the Codex Chisianus and Syro-Hexaplar Codex's version of Daniel, but does not seem to be Origen's work, supporting his recension as being the 'Old Greek' version. While the content of the Codex Chisianus, Syro-Hexaplar Codex, and Papyrus 967 are essentially the same, Papyrus 967 deviates from the others by having Daniel's visions found in chapters 7 and 8 earlier in the book, before Masoretic chapter 5, likely moved due to confusion over the identities of the two kings named Belshazzar. This translation follows the oldest documented chapter structure of Daniel, starting with the chapter of Susanna, and incorporating the Old Greek versions of Masoretic chapters 7 and 8 earlier in the book, as found in Papyrus 967. Overall, Daniel may be one of the most abused of the ancient authors, as several authors appear to have added to or redacted his work during the Persian Era. The surviving copies of Daniel are such a mess that they are generally dismissed as a work of fiction by most secular historians that research them, as they do not correspond to any version of Babylonian, Median, and Persian history, although being set in the Neo-Babylonian and Early Persian Eras. Ironically, the early sections of the Book of Daniel could only have been written in the Neo-Babylonian and early Persian eras, as the redactions that took place to the earlier sections of text only make sense in the political reality of the Early-Persian Empire.

The Book of Daniel is by far the least standardized of all the books that made it into both the Septuagint and the Masoretic Text, with no less than 16 versions surviving from the classical and early medieval eras. The Septuagint manuscripts contain two versions, the standard version found in most manuscripts, and the 'Old Greek' version, which only survives virtually complete in the Medieval era Codex Chisianus. The common translation was done by the Jewish scholar Theodotion circa 150 AD, and supplanted the Old Greek translation as it was closer to the Jewish and Christian theology of the period. The Old Greek translation was the version originally in the Septuagint, however, the authenticity and accuracy of any and all versions of the Book of Daniel have always been in doubt. The Codex Chisianus is accepted as being the closest to the Old Greek translation. It claims to be a copy of the Christian scholar Origen of Alexandria's recension from circa 240 AD, and as the Syro-Hexaplar Codex, a Syriac translation of Origen's recension from 616 and 617 AD, is virtually identical, they are both accepted as Origen's work. Origen rejected both the shorter version of Daniel found in the Hebrew and Aramaic translation that the Jews of his day were using, and Theodotion's translation, which was largely based on the Hebrew and Aramaic text, and claimed the Old Greek translation was the closest to the original text of Daniel. When Theodotion made his translation, he primarily used the shorter Hebrew and Aramaic texts that the Jews were using at the time, and filled in the missing sections by copying from the Old Greek translation. The version of Daniel found in the Masoretic Text is the shortest version of Daniel to survive to the present, and is arguably the strangest, as it is a book retained in two languages. Chapter 1, and the opening lines of chapter 2 are in Hebrew, the rest of chapter 2, as well as chapters 3 through 7 are in Aramaic, and the rest is in Hebrew. This strange combination of Hebrew and Aramaic is also present in the surviving fragments of Daniel found among in the Dead Sea Scrolls, indicating the book was already half-Hebrew and half-Aramaic by the era of the Hasmonean Dynasty, which is when the Hebrew translations of most of the other Aramaic and Canaanite (Paleo-Hebrew) books first appeared.

In the mid-3rd century BC, King Ptolemy II Philadelphus of Egypt ordered a translation of the ancient Hebrew scriptures for the Library of Alexandria. The creation of the Septuagint resulted from this order. It is generally accepted that there were several versions of the ancient Hebrew and Samaritan scriptures before the translation of the Septuagint. The Book of Odes is not believed to have been added until the 3rd-century AD, and is the only specifically Christian book to be added to the Septuagint. It includes the older Prayer of Manasseh, which was found in some copies of the Septuagint, but not all. The Prayer of Manasseh is believed to have been added in the 2nd-century BC, which is why it is not found in all copies. The current scholarly view is that it was likely written in Greek, and is not the original Prayer of Manasseh mentioned in the Septuagint's 2nd Paraleipomenon. Fragments of a different Prayer of Manasseh have been discovered among the dead sea scrolls, written in Hebrew, which could be the original, however, it is more likely that the original would have been written in Canaanite (Samaritan, Paleo-Hebrew) than Hebrew, and therefore it is still not clear which, if either, is the original Prayer of Manasseh. Most of the other songs and prayers in the Book of Odes are copied from other books found in the Septuagint, although not exactly word for word. These songs and prayers include works attributed to Moses, Hannah the mother of Samuel, King Hezekiah, the prophets Habakkuk, Isaiah, Jonah, Azariah, Hananiah, and Mishael. Additionally, the Odes includes specifically Christian prayers copied from either the Gospel of Luke, by Zechariah the father of John the Baptist, Simeon, and in some manuscripts Mary the God-Bearer.

The Book of Judges is very old, and the Song of Deborah may be the oldest surviving piece of Israelite literature. It uses some of the most archaic forms of Hebrew, and was likely composed in Canaanite before Hebrew became a defined dialect as this issue of dialect was part of the division between the Israelites during the battle between the Gileadites, east of the Jordan, and the Ephraimites from west of the Jordan. There is evidence that the book was either assembled or redacted in the Kingdom of Samaria. The region of the book also generally corresponds with the territory of the northern kingdom, both the region that had once been under Egyptian authority west of the Jordan, and the region east of the Jordan which had generally been independent of Egypt. The synchronizations between the Book of Judges and the records of Egypt are far too many to be overlooked or ignored. As almost all denominations of Christians and Jews agree that King Saul established his kingdom in 1037 BC, and the Septuagint's version of Judges includes 460 years of the land being ruled by Judges, or foreign kings, followed by an era of chaos when there was no king, the latest possible date the Exodus could have taken place was the 1500s BC, which supports the idea that the 10 plagues of Egypt were descriptions of the fallout and effects of the Minoan eruption which Egyptologists date to 1550 BC. According to Judges, 42 years later the Israelites invaded Samaria, (northern modern Israel and the Palestinian West Bank) under the leadership of Joshua, which would have been 1508 BC. The plan was already laid out in the Book of Joshua to occupy the entire land of Canaan, yet just three years later, when Joshua was 85 years old, the Israelites stopped their campaign, after having only occupied the cities in Samaria, this would have been in 1505 BC. The reason they stopped their invasion is not given, however, Egyptian records do explain it, as in the same year, 1505 BC, Pharaoh Thutmose I marched his army through Canaan to reconquer it for the Egyptian Empire. It had previously been under the control of the Hyksos Dynasty whose empire collapsed in the aftermath of the Minoan eruption. In 1550 BC, the Hyksos capital fell to the rival southern dynasty of Pharaoh Ahmose I, and the Hyksos retreated to their fortress of Sharuhen, near modern Gaza in the Palestinian Gaza Strip. This suggests the Hyksos maintained control over Canaan until Sharuhen fell to Ahmose I in 1540 BC. Ahmose I led an invasion of southern Canaan a few years later in an attempt to root out any remaining Hyksos. Egyptologists are not sure when this campaign was, placing it sometime between 1537 and 1527 BC. This campaign is not believed to have reached farther north than Byblos, in modern Lebanon, and did not result in any long-term political control over Canaan. Ahmose I's main goal seems to have been to destroy any remaining Hyksos in the region to ensure they did not try to recapture Egypt.

The book of Proverbs is generally attributed to King Solomon, who is explicitly referred to as the author of some of the proverbs. A number proverbs are known to have been copied from older collections of proverbs, most notably the Instruction of Amenemope, which was apparently written by Amenemope son of Kanakht sometime during the Ramesside Period between 1300 and 1075 BC. The Instruction of Amenemope, also called the Wisdom of Amenemopet, was an Egyptian New Kingdom era piece of wisdom literature that is generally considered a masterpiece within the genre. The Instruction of Amenemope was rediscovered by Egyptologists in 1888, after being lost for around 2400 years. Subsequently, eight partial copies have been found, ranging in estimated dates ranging between 1069 and 500 BC. The unnamed wife of Solomon who was the daughter of and Egyptian Pharoah, was likely the daughter of the last native Egyptian Pharaoh, Usermaatre Amenemope, who would have most likely carried a copy of the Instruction of Amenemope into Israel with her. The name Amenemope seems to have been quite common in ancient Egypt, and it is unlikely that the pharaoh was named after the scribe who wrote the Instruction, but, no doubt an Egyptian princess would have taken something to give her new barbarian husband, and a book called the Instruction of Amenemope, a name identical to her father's would have been a valuable gift, especially the part about not chasing after women other than his wife. Apparently, Solomon was selective in the parts of the Instruction that he chose to follow.

4ᵗʰ Maccabees is a philosophical interpretation of 2ⁿᵈ Maccabees. It was added to the Septuagint in the 1ˢᵗ century AD, however, it could have been written anywhere between 140 BC and 100 AD. This text includes more details regarding the torture of the Israelite youths from 2ⁿᵈ Maccabees, which may have come from Jason of Cyrene’s original five-volume version of Maccabees. The author of 4ᵗʰ Maccabees accepts the flying horsemen of 2ⁿᵈ Maccabees as sky messengers, which implies the Phrygian imagery was widely accepted by Jews at the time and supports the Greek and Roman records that indicate the Phrygians and Hebrews worshiped the same god. Unlike 2ⁿᵈ and 3ʳᵈ Maccabees, 4ᵗʰ Maccabees does not mention the god Dionysus/Sabaoth, indicating that the book was written in Hasmonean Dynasty or later. 4ᵗʰ Maccabees also does not have any Aramaic loanwords, indicating it was almost certainly written in Greek. Four books of Maccabees were ultimately added to the Septuagint, three in the 1ˢᵗ century BC, and the 4ᵗʰ as an appendix in the 1ˢᵗ century AD. No trace of these books has been found among the Dead Sea Scrolls, and they are generally thought to have been written in Greek. 1ˢᵗ and 2ⁿᵈ Maccabees do include several Aramaic loanwords that support an Aramaic source text. The Syriac Bibles also include a 5ᵗʰ Maccabees, which is a translation of book 6 of Josephus’ The Judean War. The Judean War is considered extended canon in the Ethiopic Bibles, however, the Ethiopic Bibles also include three books of Maccabees, which are not based on the Greek books, or Josephus. An Arabic book of Maccabees also exists, which is often mislabeled as 5ᵗʰ Maccabees in English language literature, because it was initially misidentified as being the same book as Syriac 5ᵗʰ Maccabees. The Arabic book is a translation of a Palestinian Aramaic book from circa 525 AD, which itself appears to be based on the Hebrew book of Maccabees, which surfaced much later.The Hebrew version of Maccabees was collected with other Hebrew language manuscripts from various eras in a Yiddish compilation in the 1300s. The Hebrew translation of Maccabees was likely composed in Iberia earlier than 500 AD and was probably based on an Aramaic text, along with an Iberian tale about Hannibal. The Aramaic text that was used is closely related to the text found in the Josippon, which is believed to have been composed in southern Italy in the 900s. The Josippon claims to be a copy of the book of Joseph ben Gurion, one of the leaders of the Judean Revolt of 66 AD. Joseph died in 68 AD, and Josephus, who survived the war, did not report that Joseph was a writer, however, it stands to reason his faction must have had some form of propaganda, likely based on the Maccabean Revolt. These Josippon-related versions of Maccabees are of very little historic value, as they are replete with historical errors. Their original function appears to have been to serve as inspiration rather than to educate.

The Septuagint's 4ᵗʰ Kingdoms tells the history of the kingdoms of Samaria and Judah from circa 850 BC until the Babylonians conquered Judah circa 600 BC. This era of history is well documented in the historical records of the Assyrians, Egyptians, and Babylonians, and unlike the earlier books of the Kingdoms, is generally accepted by historians. This era included the rise and fall of the Aramean Empire based in Damascus, the rise and fall of the Assyrian Empire farther north, the Assyrian wars against Egypt, and the sack of Thebes, and ultimately the rise of the Babylonian Empire. During this tumultuous time, the kingdoms of Israel, Judah, and Aram, which also appears to have been considered an Israelite kingdom by the prophet Ezekiel, struggled for survival and fell one by one to the expanding empires around them. Before the era of 4ᵗʰ Kingdoms, Samara had established an empire, occupying the Aramean kingdoms of Damascus and Hama in modern Syria, which had ended suddenly when an earthquake had leveled Samaria. The earthquake was mentioned in the Book of Amos, and archaeological evidence of it is found throughout modern northern Israel and the Palestinian West Bank. It is estimated to have been between 7.8 and 8.2 on the Richter Scale, and aftershocks likely lasted around 6 months. In the aftermath, Damascus rose to form its own Aramean empire, occupying Hama, and northern Samaria, as well as Gilead in southern modern Syria, which had been part of Samaria since the division of Israel into Samaria and Judah. However, as Assyria began to expand to the north, Samaria and Aram formed an anti-Assyria alliance, and the Samarian forces were stationed in Aram to help defend the northern border from the Assyrians. Judah was invited to join the alliance, but instead formed an alliance with the Assyrians and invaded and pillaged Samaria and southern Aram. Judah continued to be an ally of Assyria as the Assyrians conquered Aram, Samaria, and Sidon which had also allied with them. Fortunately, as Samaria finally fell to the Assyrians after a three-year campaign, the king of Assyria died, sparking a civil war between rival heirs. This civil war provided Judah with almost twenty years to build up defenses, and King Hezekiah built extensively across his kingdom. Archaeological evidence of Hezekiah's construction projects is common in the region around Jerusalem, and the southern region of the Palestinian West Bank, including the Broad Wall in Jerusalem, and the Siloam Tunnel, which connected Jerusalem with a water source outside the walls of the city. Ancient records of anti-siege artillery on the walls of Jerusalem also exist, likely ballistas or catapults, so, it is clear the Judahites knew they would be next. While the Assyrians did lay siege to Jerusalem according to 4ᵗʰ Kingdoms, they were not able to conquer the city. The Assyrian Annals record the campaign against Judah and record the cities they captured, which did not include Jerusalem, and so historians accept the general account of what happened found in 4ᵗʰ Kingdoms.

The book of Ruth appears to be part of a Samaritan story designed to splice the Moabites into the royal genealogy. The Book of Deuteronomy, which was likely written in Samaria, uses Moabite names of locations instead of Judahite names, indicating that a Moabite priesthood was active in Samaria before the kingdom fell to the Assyrians. The Book of Judges refers to King Abimelech as the bastard son of Gideon by a prostitute, which speaks volumes about his memory, however, he was an Ephrathite, as was the Abimelech in the Book of Ruth, indicating that he could not have been viewed that badly a century after his death, when Ruth’s father in law would have been born. Ruth, the step-daughter of Abimelech in the Book of Ruth, ultimately became an ancestor of King David, meaning it is possible that some Israelites were connecting the two Abimelechs in the Second Temple era, claiming that David was a descendant of King Abimelech. The setting of the Ruth is the lands of Judah and Moab in the early-1000s BC, when the Book of Judges claimed there was no king. The last judge under the Pelesets in the books of Judges was Samson's father Manoah, who ruled until 1090 BC when the Peleset Kingdom apparently collapsed. This was just over a decade before the collapse of the Egyptian New Kingdom in 1077 BC, which began the Third Intermediate Period, when Egyptian records became sparse. This collapse of civilization in Canaan and Egypt was mirrored by collapses across the Mediterranean, sparking what the Greeks would later call the Dark Age. This Dark Age is not in doubt, however, is poorly understood due to the sparse records from the era. The story would have taken place around the same era as the Benjaminite genocide in the Book of Judges, which is likely the reason the book of Ruth was placed directly behind the book of Judges in the Septuagint. It is not clear when the Book of Ruth was written, however, it is not generally considered to date back to the era it is set in. Based on the connection between the Book of Ruth and King David, it seems likely that the book was written no earlier than the era of King David, however, the book is generally dated to the time of Ezra the Scribe circa 350 BC. It is generally interpreted as an attempt to bridge the older books of Joshua and Judges with the newer books of the Kingdoms (Masoretic Samuel and Kings), which are generally accepted as having been compiled during the time of Ezra the scribe.

1ˢᵗ Maccabees tells the story of the Maccabean Revolt against the rule of the Seleucid Empire in the 2ⁿᵈ century BC. The content of 1ˢᵗ Maccabees appears to be a Sadducee text, as it gives all credit to the self-declared high priests that led the rebellion against the Greeks, occasionally mentioning the sky-god Shamayim or the earth-goddess Eretz. It also omits the names of the other gods that 2ⁿᵈ Maccabees and 3ʳᵈ Maccabees mention the Judeans worshiping, such as Dionysus, which supports its authorship in the Hasmonean Dynasty, when the other gods were no longer tolerated. Four books of Maccabees were ultimately added to the Septuagint, three in the 1ˢᵗ century BC, and the 4ᵗʰ as an appendix in the 1ˢᵗ century AD. No trace of these books has been found among the Dead Sea Scrolls, and they are generally thought to have been written in Greek. 1ˢᵗ and 2ⁿᵈ Maccabees do include several Aramaic loanwords that support an Aramaic source text.
