Deuteronomy 31:3–8

³Jehovah thy God, he will go over before thee; he will destroy these nations from before thee, and thou shalt dispossess them: and Joshua, he shall go over before thee, as Jehovah hath spoken. ⁴And Jehovah will do unto them as he did to Sihon and to Og, the kings of the Amorites, and unto their land; whom he destroyed. ⁵And Jehovah will deliver them up before you, and ye shall do unto them according unto all the commandment which I have commanded you. ⁶Be strong and of good courage, fear not, nor be affrighted at them: for Jehovah thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee. ⁷And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of good courage: for thou shalt go with this people into the land which Jehovah hath sworn unto their fathers to give them; and thou shalt cause them to inherit it. ⁸And Jehovah, he it is that doth go before thee; he will be with thee, he will not fail thee, neither forsake thee: fear not, neither be dismayed.
