Deuteronomy 31:3-7

3The Lord your God is the one who will cross the river ahead of you. He will destroy those nations as you arrive, and you will take possession of their land. Joshua will also cross the river ahead of you, as the Lord told you.

4The Lord will do to those nations what he did to King Sihon and King Og of the Amorites and to their lands when he destroyed them.

5The Lord will hand them over to you, and you must do to them everything that I commanded you.

6Be strong and courageous. Don’t tremble! Don’t be afraid of them! The Lord your God is the one who is going with you. He won’t abandon you or leave you.”

7Then Moses called for Joshua and said to him in the presence of all Israel, “Be strong and courageous. You will go with these people into the land that the Lord will give them, as he swore to their ancestors. You will help them take possession of the land.
