Numbers 21:34-35

Young's Literal Translation

³⁴ And Jehovah saith unto Moses, `Fear him not, for into thy hand I have given him, and all his people, and his land, and thou hast done to him as thou hast done to Sihon king of the Amorite, who is dwelling in Heshbon.'

³⁵ And they smite him, and his sons, and all his people, until he hath not left to him a remnant, and they possess his land.
