311 And Moses went and spoke these words to all Israel; 2 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 Jehovah hath said unto me, Thou shalt not go over this Jordan. 3 Jehovah thy God, he will go over before thee, he will destroy these nations from before thee, that thou mayest take possession of them: Joshua, he shall go over before thee, as Jehovah hath said. 4 And Jehovah will do to them as he did to Sihon and to Og, the kings of the Amorites, and to their land; whom he destroyed. 5 And when Jehovah giveth them up before you, ye shall do to them according to all the commandment which I have commanded you. 6 Be strong and courageous, fear them not, neither be afraid of them; for Jehovah thy God, he it is that goeth with thee; he will not leave thee, nor forsake thee.

Commentary on Deuteronomy 31:1-8
(Read Deuteronomy 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, Hebrews 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.
