The oldest surviving physical copy of Esther is found in the Codex Vaticanus, which dates to circa 350 AD. The version of Ether in the Codex Vaticanus is generally accepted as being the original version added to the Septuagint sometime in the 2ⁿᵈ century BC, however, it claims to have not been translated in Alexandria, like the rest of the Septuagint. There are two other early copies of the common version of Esther found in the Codex Vaticanus, the copy in the Codex Sinaiticus from circa 350 AD, Codex Alexandrinus from circa 450 AD. The term ‘king of the gods’ is found in chapter 4 of the Vaticanus version of Esther, however, does not make sense in the theology that developed in later Judaism, in which there was only one God, indicating the early date of the original composition. The title ‘king of the gods’ was used by Esther in the book, who use the title to refer to the god of the Israelite. While Esther was described as being the Queen (or royal consort) in the texts, she was also described as being a devote worshiped of the Israelite god, and ‘King of the gods’ was not a Zoroastrian title of Ahura Mazda either, as Zoroastrianism was also monotheistic, meaning that this title has to be traced back to the Israelite religion.
