'Kings' in the Bible

And we took the land at that time out of the hand of the two kings of the Amorites that were beyond the Jordan, from the valley of the Arnon unto mount Hermon;

And I commanded Joshua at that time, saying, Thine eyes have seen all that Jehovah your God hath done unto these two kings: so shall Jehovah do unto all the kingdoms whither thou goest over.

And they took his land in possession, and the land of Og king of Bashan, the two kings of the Amorites, who were beyond the Jordan toward the sunrising;

And he will deliver their kings into thy hand, and thou shalt make their name to perish from under heaven: there shall no man be able to stand before thee, until thou have destroyed them.

And Jehovah will do unto them as he did to Sihon and to Og, the kings of the Amorites, and unto their land; whom he destroyed.
