Deuteronomy 31:2-3

31:2 He said to them, “Today I am a hundred and twenty years old. I am no longer able to get about, and the Lord has said to me, ‘You will not cross the Jordan.’ 31:3 As for the Lord your God, he is about to cross over before you; he will destroy these nations before you and dispossess them. As for Joshua, he is about to cross before you just as the Lord has said.

tn Or “am no longer able to lead you” (NIV, NLT); Heb “am no longer able to go out and come in.”
