Deuteronomy 31:1-31:3

And Moses went and spoke these words unto all Israel. And he said unto them: "I am a hundred and twenty years old this day; I can no more go out and come in; and HaShem hath said unto me: Thou shalt not go over this Jordan. "HaShem thy G-d, He will go over before thee; He will destroy these nations from before thee, and thou shalt dispossess them; and Joshua, he shall go over before thee, as HaShem hath spoken."
