Deuteronomy 31:3-5

Amplified Bible

³ It is the Lord your God who will cross ahead of you; He will destroy these nations before you, and you shall dispossess them. Joshua is the one who will go across before you [to lead you], just as the Lord has said. ⁴ The Lord will do to them just as He did to Sihon and Og, the kings of the Amorites, and to their land, when He destroyed them. ⁵ The Lord will hand them over to you, and you shall do to them in accordance with all the commandments which I have commanded you.
