Deuteronomy 31:4-6

New Revised Standard Version, Anglicised Catholic Edition

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. ⁶ Be strong and bold; have no fear or dread of them, because it is the Lord your God who goes with you; he will not fail you or forsake you.’
