'Kings' in the Bible

So at that time we took the land of the two Amorite kings in the Transjordan from Wadi Arnon to Mount Hermon

I also commanded Joshua at the same time, "You have seen everything the Lord your God did to these two kings; he will do the same to all the kingdoms where you are going.

They possessed his land and that of King Og of Bashan -- both of whom were Amorite kings in the Transjordan, to the east.

He will hand over their kings to you and you will erase their very names from memory. Nobody will be able to resist you until you destroy them.

The Lord will do to them just what he did to Sihon and Og, the Amorite kings, and to their land, which he destroyed.
