Deuteronomy 31:3-5

New Revised Standard Version, Anglicised

³ The Lord your God himself will cross over before you. He will destroy these nations before you, and you shall dispossess them. Joshua also will cross over before you, as the Lord promised. ⁴ The Lord will do to them as he did to Sihon and Og, the kings of the Amorites, and to their land, when he destroyed them. ⁵ The Lord will give them over to you and you shall deal with them in full accord with the command that I have given to you.
