15 until Jehovah have given your brethren rest, as [he hath given] you, and they also have possessed the land which Jehovah your God giveth them: then ye shall return unto the land of your possession, and possess it, which Moses the servant of Jehovah gave you beyond the Jordan toward the sunrising.
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.
