Deuteronomy 31:4-6

Darby Translation

⁴ And Jehovah will do to them as he did to Sihon and to Og, the kings of the Amorites, and to their land; whom he destroyed.

⁵ And when Jehovah giveth them up before you, ye shall do to them according to all the commandment which I have commanded you.

⁶ Be strong and courageous, fear them not, neither be afraid of them; for Jehovah thy God, he it is that goeth with thee; he will not leave thee, nor forsake thee.
