Numbers 21:32-35

32Now Moses sent men to spy out 1Jazer, and they captured its villages and dispossessed the Amorites who were there.

332Then they turned and went up by the way of Bashan, and Og the king of Bashan went out against them 3with all his people, for battle at 4Edrei. 34But the Lord said to Moses, “5Do not fear him, for I have handed him over to you, and all his people and his land; and you shall do to him as you did to Sihon, king of the Amorites, who lived in Heshbon.” 35So 6they 7killed him and his sons and all his people, until there was no survivor left; and they took possession of his land.
