'Kings' in the Bible

"And so we took at that time the land from {the control of} [the] two kings of the Amorites who [were] {on the other side of the Jordan}, from the wadi of Arnon up to {Mount Hermon}.

And I commanded Joshua at that time, saying, 'Your eyes see all that Yahweh your God has done to these two kings; so Yahweh will do to all [of] the kingdoms where you are about to cross over to.

And [so] they took possession of his land and the land of Og king of Bashan, the two kings of the Amorites who [were] beyond the Jordan, {eastward},

And he will give their kings into your hand, and you shall blot out their names from under the heaven; anyone will not [be able to] stand {against you} {until you destroy them}.

And Yahweh will do to them [just] as he did to Sihon and to Og, kings of the Amorites, and to their land, which he destroyed with them.
