Deuteronomy 31:6-11

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.

9And Moses wrote this law, and delivered it unto the priests the sons of Levi, that bare the ark of the covenant of Jehovah, and unto all the elders of Israel. 10And Moses commanded them, saying, At the end of every seven years, in the set time of the year of release, in the feast of tabernacles, 11when all Israel is come to appear before Jehovah thy God in the place which he shall choose, thou shalt read this law before all Israel in their hearing.
