'Kings' in the Bible

"So the children went in and possessed the land, and you subdued before them the inhabitants of the land, the Canaanites, and gave them into their hands, with their kings, and the peoples of the land, that they might do with them as they pleased.

Now therefore, our God, the great, the mighty, and the awesome God, who keeps covenant and loving kindness, don't let all the travail seem little before you, that has come on us, on our kings, on our princes, and on our priests, and on our prophets, and on our fathers, and on all your people, since the time of the kings of Assyria to this day.

neither have our kings, our princes, our priests, nor our fathers, kept your law, nor listened to your commandments and your testimonies with which you testified against them.

It yields much increase to the kings whom you have set over us because of our sins: also they have power over our bodies, and over our livestock, at their pleasure, and we are in great distress.
