'Kings' in the Bible

When all the kings who were Hadadezer’s subjects saw that they had been defeated by Israel, they made peace with Israel and became their subjects. After this, the Arameans were afraid to ever help the Ammonites again.

In the spring when kings march out to war, David sent Joab with his officers and all Israel. They destroyed the Ammonites and besieged Rabbah, but David remained in Jerusalem.
