'Kings' in the Bible

Now these are the kings who reigned in the land of Edom before any king of the sons of Israel reigned. Bela was the son of Beor, and the name of his city was Dinhabah.

So all Israel was enrolled by genealogies; and behold, they are written in the Book of the Kings of Israel. And Judah was carried away into exile to Babylon for their unfaithfulness.

He permitted no man to oppress them,And He reproved kings for their sakes, saying,

The sons of Ammon came out and drew up in battle array at the entrance of the city, and the kings who had come were by themselves in the field.

Then it happened in the spring, at the time when kings go out to battle, that Joab led out the army and ravaged the land of the sons of Ammon, and came and besieged Rabbah. But David stayed at Jerusalem. And Joab struck Rabbah and overthrew it.
