Deuteronomy 31:9

5 The LORD will deliver them over to you, and you must do to them exactly as I have commanded you.

6 Be strong and courageous; do not be afraid or terrified of them, for it is the LORD your God who goes with you; He will never leave you nor forsake you.”

7 Then Moses called for Joshua and said to him in the presence of all Israel, “Be strong and courageous, for you will go with this people into the land that the LORD swore to their fathers to give them, and you shall give it to them as an inheritance.

8 The LORD Himself goes before you; He will be with you. He will never leave you nor forsake you. Do not be afraid or discouraged.”

9 So Moses wrote down 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.

10 Then Moses commanded them, “At the end of every seven years, at the appointed time in the year of remission of debt, during the Feast of Tabernacles,

11 when all Israel comes before the LORD your God at the place He will choose, you are to read this law in the hearing of all Israel.

12 Assemble the people—men, women, children, and the foreigners within your gates—so that they may listen and learn to fear the LORD your God and to follow carefully all the words of this law.

13 Then their children who do not know the law will listen and learn to fear the LORD your God, as long as you live in the land that you are crossing the Jordan to possess.”
