Deuteronomy 31:3-5

Darby Translation

³ Jehovah thy God, he will go over before thee, he will destroy these nations from before thee, that thou mayest take possession of them: Joshua, he shall go over before thee, as Jehovah hath said.

⁴ And Jehovah will do to them as he did to Sihon and to Og, the kings of the Amorites, and to their land; whom he destroyed.

⁵ And when Jehovah giveth them up before you, ye shall do to them according to all the commandment which I have commanded you.
