15 until Jehovah give your brethren rest as to you, and they also take possession of the land which Jehovah your God giveth them; then shall ye return into the land of your possession and possess it, which Moses the servant of Jehovah gave you on this side of the Jordan toward the sun-rising.
Matthew Henry's Commentary on Joshua 1:15
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.
