9 Have I not commanded thee: Be strong and courageous? Be not afraid, neither be dismayed; for Jehovah thy God is with thee whithersoever thou goest.

10 And Joshua commanded the officers of the people, saying, 11 Go through the midst of the camp, and command the people, saying, Prepare yourselves victuals, for in three days ye shall pass over this Jordan, that ye may enter in to take possession of the land which Jehovah your God giveth you to possess it.

Matthew Henry's Commentary on Joshua 1:9-11

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.

Commentary on Joshua 1:10-15

(Read Joshua 1:10-15)

Joshua says to the people, Ye shall pass over Jordan, and shall possess the land; because God had said so to him. We honour the truth of God, when we stagger not at the promise of God. The two tribes and a half were to go over Jordan with their brethren. When God, by his providence, has given us rest, we ought to consider what service we may do to our brethren.
