6 Be strong and courageous, because you will lead these people to inherit the land I swore to their ancestors to give them.

Matthew Henry's Commentary on Joshua 1:6

Commentary on Joshua 1:5-9

(Read Joshua 1:5-9)

Joshua is to make the law of God his rule. He is charged to meditate therein day and night, that he might understand it. Whatever affairs of this world we have to mind, we must not neglect the one thing needful. All his orders to the people, and his judgments, must be according to the law of God. Joshua must himself be under command; no man's dignity or dominion sets him above the law of God. He is to encourage himself with the promise and presence of God. Let not the sense of thine own infirmities dishearten thee; God is all-sufficient. I have commanded, called, and commissioned thee to do it, and will be sure to bear thee out in it. When we are in the way of duty, we have reason to be strong and very bold. Our Lord Jesus, as Joshua here, was borne up under his sufferings by a regard to the will of God, and the commandment from his Father.

6 Be strong and courageous. Do not be afraid or terrified because of them, for the Lord your God goes with you; he will never leave you nor forsake you." 7 Then Moses summoned Joshua and said to him in the presence of all Israel, "Be strong and courageous, for you must go with this people into the land that the Lord swore to their ancestors to give them, and you must divide it among them as their inheritance. 8 The Lord himself goes before you and will be with you; he will never leave you nor forsake you. Do not be afraid; do not be discouraged."

Matthew Henry's Commentary on Deuteronomy 31:6-8

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.
