Deuteronomy 31:6

³The Lord thy God, he will go over before thee, and he will destroy these nations from before thee, and thou shalt possess them: and Joshua, he shall go over before thee, as the Lord hath said. ⁴And the Lord shall do unto them as he did to Sihon and to Og, kings of the Amorites, and unto the land of them, whom he destroyed. ⁵And the Lord shall give them up before your face, that ye may do unto them according unto all the commandments which I have commanded you. ⁶Be strong and of a good courage, fear not, nor be afraid of them: for the Lord 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 a good courage: for thou must go with this people unto the land which the Lord hath sworn unto their fathers to give them; and thou shalt cause them to inherit it. ⁸And the Lord, 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. ⁹And Moses wrote this law, and delivered it unto the priests the sons of Levi, which bare the ark of the covenant of the Lord, and unto all the elders of Israel.
