Books of Kings, two books of the Hebrew Bible or the Protestant Old Testament that, together with Deuteronomy, Joshua, Judges, and 1 and 2 Samuel, belong to the group of historical books (Deuteronomic history) written during the Babylonian Exile (c. 550 BC) of the Jews. (In most Roman Catholic versions, 1 and 2 Samuel are called the first and second books of Kings, and the two Hebrew and Protestant books of Kings are called the third and fourth books of Kings.)
