Deuteronomy 31:7-9

American Standard Version

⁷ And 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. ⁸ And 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.

⁹ And 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.
