Numbers 21:34-35 Common English Bible (CEB)
34 The Lord said to Moses: Don’t be afraid of him, for I have handed over all his people and his land. Do to him as you did to Sihon the Amorite king who ruled in Heshbon.
35 They slaughtered Og, his sons, and all his people until there were no survivors. Then they took possession of his land.
