Deuteronomy 31:4-6

Young's Literal Translation

⁴ and Jehovah hath done to them as he hath done to Sihon and to Og, kings of the Amorite, and to their land, whom He destroyed.

⁵ And Jehovah hath given them before your face, and ye have done to them according to all the command which I have commanded you;

⁶ be strong and courageous, fear not, nor be terrified because of them, for Jehovah thy God [is] He who is going with thee; He doth not fail thee nor forsake thee.'
