“Like the two books of Samuel and Chrinicles, the two books of Kings were originally written as one book, by an unknown writer. They were separated into two books when the Hebrew text was translated for Greek-speaking Jews in about 300 BC.”

“It’s uncertain exactly when the stories were compiled into a single book. Many scholars suspect it was in the mid-500s BC, after the Babylonians had destroyed Jerusalem and dragged off much of the Jewish population into excile.”
