Deuteronomy 3:1-3

1Then we turned and we went along the road towards Bashan. Og, king of Bashan, marched out with his whole army to attack us at Edrei.

2But the Lord said to me, ‘Do not be afraid of him. I have given him to you with his whole army and his land. You must do the same thing to Og as you did to Sihon, king of the Amorites, who ruled in Heshbon.’

3So the Lord our God put Og, king of Bashan, under our power, as well as his whole army. We killed them all so that we left no one alive.
