Deuteronomy 31:3; Deuteronomy 31:7; Deuteronomy 31:23

3 The LORD your God himself will cross over ahead of you. He will destroy these nations before you, and you will take possession of their land. Joshua also will cross over ahead of you, as the LORD said.

7 Then Moses summoned Joshua and said to him in the presence of all Israel, “Be strong and courageous, for you must go with this people into the land that the LORD swore to their ancestors to give them, and you must divide it among them as their inheritance.

23 The LORD gave this command to Joshua son of Nun: “Be strong and courageous, for you will bring the Israelites into the land I promised them on oath, and I myself will be with you.”
