Deuteronomy 31:3-5, 7-8, 23

“GOD, your God, will cross the river ahead of you and destroy the nations in your path so that you may oust them. (And Joshua will cross the river before you, as GOD said he would.) GOD will give the nations the same treatment he gave the kings of the Amorites, Sihon and Og, and their land; he’ll destroy them. GOD will hand the nations over to you, and you’ll treat them exactly as I have commanded you.

Then Moses summoned Joshua. He said to him with all Israel watching, “Be strong. Take courage. You will enter the land with this people, this land that GOD promised their ancestors that he’d give them. You will make them the proud possessors of it. GOD is striding ahead of you. He’s right there with you. He won’t let you down; he won’t leave you. Don’t be intimidated. Don’t worry.” * * *

Then GOD commanded Joshua son of Nun saying, “Be strong. Take courage. You will lead the People of Israel into the land I promised to give them. And I’ll be right there with you.”
