Cyrus
Chronicles 15:13 has a lot to say beyond what is celebrated on Purim
All who would not seek the LORD, the God of Israel, were to be put to death, whether small or great, man or woman.
What is the “Chronicles ?” (parts from Wikipedia)
A late addition to Jewish historical writings, possibly authored by Ezra .. an appointee of Cyrus the Great. The translators who created the Greek version of the Hebrew Bible (the Septuagint) called this book “Things Left Out”, indicating that they thought of it as a supplement to another work, probably Genesis-Kings. Recent suggestions have been that it was intended as a clarification of the history in Genesis-Kings, or a replacement or alternative for it.
The association with Cyrus is very important. After his conquest of Babylon, Cyrus released the hostages form Kingdoms conquered by the Babylonians. Under Cyrus’ instructions, Ezra led the elite of Babylon back from exile after the Persian Conquest. Since then Cyrus has been called the “messiah” by Jews. The last events in Chronicles take place in the reign of Cyrus the Great, the Persian king who conquered Babylon in 539 BC; this sets an earliest possible date for the book. It was probably composed between 400–250 BC, with the period 350–300 BC the most likely. The latest person mentioned in Chronicles is Anani of the eighth generation of King Jehoiachin. Anani’s birth would likely have been sometime between 425 and 400 BC.
Chronicles appears to be largely the work of a single individual, with some later additions and editing. The writer was probably male, probably a Levite (temple priest), and probably from Jerusalem. He was well read, a skilled editor, and a sophisticated theologian. His intention was to use Israel’s past to convey religious messages to his peers, the literary and political elite of Jerusalem in the time of the Persian empire.
Jewish and Christian tradition identified this author as the 5th century BC figure Ezra, who gives his name to the Book of Ezra; Ezra was also believed to be the author of both Chronicles and Ezra-Nehemiah, but later critical scholarship abandoned the identification with Ezra and called the anonymous author the Chronicler. The last half of the 20th century saw a radical reappraisal, and many now regard it as improbable that the author of Chronicles was also the author of the narrative portions of Ezra-Nehemiah.[7] Nevertheless, one of the most striking, although inconclusive, features of Chronicles is that its closing sentence is repeated as the opening of Ezra-Nehemiah.
