Deuteronomy 31:3-5

New Century Version

³ the Lord your God will lead you across himself. He will destroy those nations for you, and you will take over their land. Joshua will also lead you across, as the Lord has said. ⁴ The Lord will do to those nations what he did to Sihon and Og, the kings of the Amorites, when he destroyed them and their land. ⁵ The Lord will give those nations to you; do to them everything I told you.
