'Kings' in the Bible

And these are the kings who reigned in the land of Edom before the reigning of a king of the sons of Israel: Bela son of Beor, and the name of his city is Dinhabah.

And all Israel have reckoned themselves by genealogy, and lo, they are written on the book of the kings of Israel and Judah -- they were removed to Babylon for their trespass.

He hath not suffered any to oppress them, And reproveth on their account kings:

and the sons of Ammon come out and set battle in array at the opening of the city, and the kings who have come are by themselves in the field.
