Deuteronomy 31:1-8

Moses again spoke to the whole nation of Israel: I am 120 years old, and I am no longer able to be your leader. And besides that, the LORD your God has told me that he won't let me cross the Jordan River. But he has promised that he and Joshua will lead you across the Jordan to attack the nations that live on the other side. The LORD will destroy those nations just as he destroyed Sihon and Og, those two Amorite kings. Just remember—whenever you capture a place, kill everyone who lives there. Be brave and strong! Don't be afraid of the nations on the other side of the Jordan. The LORD your God will always be at your side, and he will never abandon you. Then Moses called Joshua up in front of the crowd and said: Joshua, be brave and strong as you lead these people into their land. The LORD made a promise long ago to Israel's ancestors that this land would someday belong to Israel. That time has now come, and you must divide up the land among the people. The LORD will lead you into the land. He will always be with you and help you, so don't ever be afraid of your enemies.
