that this may be a sign among you, that when your children ask in time to come, saying, What do you mean by these stones?
      I. God gave orders for the preparing of this memorial. Had Joshua done it without divine direction, it might have looked like a design to perpetuate his own name and honour, nor would it have commanded so sacred and venerable a regard from posterity as now, when god himself appointed it. Note, God's works of wonder ought to be kept in everlasting remembrance, and means devise for the preserving of the memorial of them. Some of the Israelites that passed over Jordan perhaps were so stupid, and so little affected with this great favour of God to them, that they felt no concern to have it remembered; while others, it may be, were so much affected with it, and had such deep impressions made upon them by it, that they thought there needed no memorial of it to be erected, the heart and tongue of every Israelite in every age would be a living lasting monument of it. But God, knowing their frame, and how apt they had been soon to forget his works, ordered an expedient for the keeping of this in remembrance to all generations, that those who could not, or would not, read the record of it in the sacred history, might come to the knowledge of it by the monument set up in remembrance of it, of which the common tradition of the country would be an explication; it would likewise serve to corroborate the proof of the matter of fact, and would remain a standing evidence of it to those who in after-ages might question the truth of it. A monument is to be erected, and, 1. Joshua, as chief captain, must five direction about it (Joshua 4:1; Joshua 4:1): When all the people had clean passed over Jordan, not even the feeble, that were the hindmost of them, left behind, so that God had done his work completely, and every Israelite got safe into Canaan, then God spoke unto Joshua to provide materials for this monument. It is the pious conjecture of the learned bishop Patrick that Joshua had gone into some place of retirement to return thanks immediately for this wonderful mercy, and then god met him, and spoke thus to him. Or, perhaps, it was by Eleazar the priest that God gave these and other instructions to Joshua; for, though he is not mentioned here, yet, when Joshua was ordained by the imposition of hands to this great trust, god appointed that Eleazar should ask counsel for him after the judgment of Urim, and at his word Joshua and all the children of Israel must go out and come in,Numbers 27:21. 2. One man out of each tribe, and he a chosen man, must be employed to prepare materials for this monument, that each tribe might have the story told them by one of themselves, and each tribe might contribute something to the glory of God thereby (Joshua 4:2; Joshua 4:4): Out of ever tribe a man. Not the Levites only, but every Israelite must, in his place, help to make known to the sons of men God's mighty acts,Psalms 145:12. The two tribes, though seated already in their possession, yet, sharing in the mercy, must lend a hand to the memorial of it. 3. The stones that must be set up for this memorial are ordered to be taken out of the midst of the channel (where, probably, there lay abundance of great stones), and as near as might be from the very place where the priests stood with the ark,Joshua 4:3; Joshua 4:5. This intended monument deserved to be made of stones curiously cut with the finest and most exquisite art, but these stones out of the bottom of the river were more natural and more apt indications of the miracle. let posterity know by this that Jordan was driven back, for these very stones were then fetched out of it. In the institution of signs, God always chose that which was most proper and significant, rather than that which is pompous or curious; for God hath chosen the foolish things of the world. These twelve men, after they got over Jordan, must be sent back to the place where the ark stood, being permitted to come near it (which others might not) for this service: "Pass over before the ark (Joshua 4:5; Joshua 4:5), that is, into the presence of the ark, which now stands in the midst of Jordan, and thence fetch these stones." 4. The use of these stones is here appointed for a sign (Joshua 4:6; Joshua 4:6), a memorial, Joshua 4:7; Joshua 4:7. They would give occasion to the children to ask their parents in time to come, How came these stones hither? (probably the land about not being stony), and then the parents would inform them, as they themselves had been informed, that in this place Jordan was divided by the almighty power of God, to give Israel passage into Canaan, as Joshua enlarges on this head, Joshua 4:22-24; Joshua 4:22-24, c.
