311 When Moses had finished giving these instructions to all the people of Israel, 2 he said, "I am now 120Â years old, and I am no longer able to lead you. The Lord has told me, 'You will not cross the Jordan River.' 3 But the Lord your God himself will cross over ahead of you. He will destroy the nations living there, and you will take possession of their land. Joshua will lead you across the river, just as the Lord promised. 4 "The Lord will destroy the nations living in the land, just as he destroyed Sihon and Og, the kings of the Amorites. 5 The Lord will hand over to you the people who live there, and you must deal with them as I have commanded you. 6 So be strong and courageous! Do not be afraid and do not panic before them. For the Lord your God will personally go ahead of you. He will neither fail you nor abandon you."

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.
