Deuteronomy 31:2-4 King James Version (KJV)
2 And he said unto them, I am an hundred and twenty years old this day; I can no more go out and come in: also the Lord hath said unto me, Thou shalt not go over this Jordan.
3 The Lord thy God, he will go over before thee, and he will destroy these nations from before thee, and thou shalt possess them: and Joshua, he shall go over before thee, as the Lord hath said.
4 And the Lord shall do unto them as he did to Sihon and to Og, kings of the Amorites, and unto the land of them, whom he destroyed.
Deuteronomy 31:2-4 New International Version (NIV)
2 “I am now a hundred and twenty years old and I am no longer able to lead you. The Lord has said to me, ‘You shall not cross the Jordan.’ 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. 4 And the Lord will do to them what he did to Sihon and Og, the kings of the Amorites, whom he destroyed along with their land.
