Deuteronomy 31:2-4 World English Bible (WEB)
2 He said to them, “I am one hundred twenty years old today. I can no more go out and come in. Yahweh has said to me, ‘You shall not go over this Jordan.’ 3 Yahweh your God himself will go over before you. He will destroy these nations from before you, and you shall dispossess them. Joshua will go over before you, as Yahweh has spoken. 4 Yahweh will do to them as he did to Sihon and to Og, the kings of the Amorites, and to their land, when he destroyed them.
