Deuteronomy 31:4-6

Amplified Bible

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. ⁶ Be strong and courageous, do not be afraid or tremble in dread before them, for it is the Lord your God who goes with you. He will not fail you or abandon you.”
