'Kings' in the Bible

When all the kings who were subject to Hadadezer saw they were defeated by Israel, they made peace with Israel and became subjects of Israel. The Arameans were no longer willing to help the Ammonites.

In the spring of the year, at the time when kings normally conduct wars, David sent out Joab with his officers and the entire Israelite army. They defeated the Ammonites and besieged Rabbah. But David stayed behind in Jerusalem.
