Deuteronomy 31:4-6

Revised Standard Version

⁴ And 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 And the Lord will give them over to you, and you shall do to them according to all the commandment which I have commanded you. ⁶ Be strong and of good courage, do not fear or be in dread of them: for it is the Lord your God who goes with you; he will not fail you or forsake you.”
