Deuteronomy 3:2-3

Webster(i) 2 And the LORD said to me, Fear him not: for I will deliver him, and all his people, and his land, into thy hand; and thou shalt do to him as thou didst to Sihon king of the Amorites, who dwelt at Heshbon. 3 So the LORD our God delivered into our hands Og also the king of Bashan, and all his people: and we smote him until none was left to him remaining.
