31:2 And he said unto them, I [am] an hundred and twenty years old this day; I {a} can no more go out and come in: also the LORD hath said unto me, Thou shalt not go over this Jordan.
(a) I can no longer execute my office.
31:2 Go out and come in - Perform the office of a leader or governor, because the time of my death approaches.
31:1-8 Moses assures Israel of the constant presence of God with them. This is applied by the apostle to all God's spiritual Israel, to encourage their faith and hope; unto us is this gospel preached, as well as unto them; he will never fail thee, nor forsake thee, Heb 13:5. Moses commends Joshua to them for a leader; one whose wisdom, and courage, and affection they had long known; one whom God had appointed to be their leader; and therefore would own and bless. Joshua is well pleased to be admonished by Moses to be strong and of good courage. Those shall speed well, who have God with them; therefore they ought to be of good courage. Through God let us do valiantly, for through him we shall do victoriously; if we resist the devil, he will flee from us.
