6 "Be strong. Take courage. Don't be intimidated. Don't give them a second thought because God, your God, is striding ahead of you. He's right there with you. He won't let you down; he won't leave you." 7 Then Moses summoned Joshua. He said to him with all Israel watching, "Be strong. Take courage. You will enter the land with this people, this land that God promised their ancestors that he'd give them. You will make them the proud possessors of it. 8 God is striding ahead of you. He's right there with you. He won't let you down; he won't leave you. Don't be intimidated. Don't worry."

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.
