Numbers 21:34-35

American Standard Version

³⁴ And Jehovah said unto Moses, Fear him not: for I have delivered him into thy hand, and all his people, and his land; and thou shalt do to him as thou didst unto Sihon king of the Amorites, who dwelt at Heshbon. ³⁵ So they smote him, and his sons and all his people, until there was none left him remaining: and they possessed his land.
