I. God speaks to Joshua to put honour upon him, v. 7, 8. 1. It was a great honour God did him that he spoke to him as he had done to Moses from off the mercy-seat, before the priests removed it with the ark. This would make Joshua easy in himself and great among the people, that God was pleased to speak so familiarly to him. 2. That he designed to magnify him in the sight of all Israel. He had told him before that he would be with him (ch. i. 5), and that comforted him, but now all Israel shall see it, and this would magnify him. Those are truly great with whom God is and whom he employs and owns in his service. God magnified him because he would have the people magnify him. Pious magistrates are to be highly honoured and esteemed as public blessings, and the more we see of God with them the more we should honour them. By the dividing of the Red Sea Israel was convinced that God was with Moses in bringing them out of Egypt; therefore they are said to be baptized unto Moses in the sea, 1 Cor. x. 2. And upon that occasion they believed him, Exod. xiv. 31. And now, by the dividing of Jordan, they shall be convinced that God is in like manner with Joshua in bringing them into Canaan. God had magnified Joshua before on several occasions, but now he began to magnify him as the successor of Moses in the government. Some have observed that it was at the banks of Jordan that God began to magnify Joshua, and at the same place he began to magnify our Lord Jesus as Mediator; for John was baptizing at Bethabara, the house of passage, and there it was that when our Saviour was baptized it was proclaimed concerning him, This is my beloved Son. 3. That by him he gave orders to the priests themselves, though they were his immediate attendants (v. 8): Thou shalt command the priests, that is, "Thou shalt make known to them the divine command in this matter, and take care that they observe it, to stand still at the brink of Jordan while the waters part, that it may appear to be at the presence of the Lord, of the mighty God of Jacob, that Jordan is driven back," Ps. cxiv. 5, 7. God could have divided the river without the priests, but they could not without him. The priests must herein set a good example to the people, and teach them to do their utmost in the service of God, and trust him for help in time of need.
