Deuteronomy 31:7-9

Amplified Bible

⁷ Then Moses called to Joshua and said to him in the sight of all [the people of] Israel, “Be strong and courageous, for you will go with this people into the land which the Lord has sworn to their fathers to give them, and you will give it to them as an inheritance. ⁸ It is the Lord who goes before you; He will be with you. He will not fail you or abandon you. Do not fear or be dismayed.”

⁹ So Moses wrote this law and gave it to the priests, the sons of Levi who carried the ark of the covenant of the Lord, and to all the elders of Israel.
