Deuteronomy 31:6-11

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 to Joshua, and said to him in the sight of all Israel, Be strong and of a good courage: for thou must go with this people to the land which the LORD hath sworn to 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 to the priests the sons of Levi, who bore the ark of the covenant of the LORD, and to all the elders of Israel. 10And Moses commanded them, saying, At the end of every seven years, in the solemnity of the year of release, in the feast of tabernacles, 11When all Israel is come to appear before the LORD thy God in the place which he shall choose, thou shalt read this law before all Israel in their hearing.
