'Kings' in the Bible

So the children went in and possessed the land, and thou subduedst before them the inhabitants of the land, the Canaanites, and gavest them into their hands, with their kings, and the peoples of the land, that they might do with them as they would.

Now therefore, our God, the great, the mighty, and the terrible God, who keepest covenant and lovingkindness, let not all the travail seem little before thee, that hath come upon us, on our kings, on our princes, and on our priests, and on our prophets, and on our fathers, and on all thy people, since the time of the kings of Assyria unto this day.

neither have our kings, our princes, our priests, nor our fathers, kept thy law, nor hearkened unto thy commandments and thy testimonies wherewith thou didst testify against them.

And it yieldeth much increase unto the kings whom thou hast set over us because of our sins: also they have power over our bodies, and over our cattle, at their pleasure, and we are in great distress.
