Jos 4:9-24 And Joshua set up twelve stones in the midst of the Jordan, in the place where the feet of the priests bearing the ark of the covenant had stood; and they are there to this day. For the priests bearing the ark stood in the midst of the Jordan until everything was finished that the LORD commanded Joshua to tell the people, according to all that Moses had commanded Joshua. The people passed over in haste. And when all the people had finished passing over, the ark of the LORD and the priests passed over before the people. The sons of Reuben and the sons of Gad and the half-tribe of Manasseh passed over armed before the people of Israel, as Moses had told them. About 40,000 ready for war passed over before the LORD for battle, to the plains of Jericho. On that day the LORD exalted Joshua in the sight of all Israel, and they stood in awe of him just as they had stood in awe of Moses, all the days of his life. And the LORD said to Joshua, “Command the priests bearing the ark of the testimony to come up out of the Jordan.” So Joshua commanded the priests, “Come up out of the Jordan.” And when the priests bearing the ark of the covenant of the LORD came up from the midst of the Jordan, and the soles of the priests’ feet were lifted up on dry ground, the waters of the Jordan returned to their place and overflowed all its banks, as before. The people came up out of the Jordan on the tenth day of the first month, and they encamped at Gilgal on the east border of Jericho. And those twelve stones, which they took out of the Jordan, Joshua set up at Gilgal. And he said to the people of Israel, “When your children ask their fathers in times to come, ‘What do these stones mean?’ then you shall let your children know, ‘Israel passed over this Jordan on dry ground.’ For the LORD your God dried up the waters of the Jordan for you until you passed over, as the LORD your God did to the Red Sea, which he dried up for us until we passed over, so that all the peoples of the earth may know that the hand of the LORD is mighty, that you may fear the LORD your God forever.”
When all were over, then came the twelve and Joshua, who would spend some time in gathering the stones and rearing the memorial in the river-bed. Through all the stir the ark was still. Over all the march it watched. So long as one Israelite was in the channel it remained, a silent presence, to ensure his safety. It let their rate of speed determine the length of its standing there. It waited for the slowest foot and the weariest laggard. God makes His ‘very present help’ of the same length as our necessities, and lets us beat the time to which He conforms. Not till the last loiterer has struggled to the farther shore does He cease by His presence to keep His people safe on the strange road which by His presence He has opened for them.
The form of the miracle was a condescension to weak faith, to which help was ministered by giving sense something to grasp. It was easier to believe that the torrent would not rush down on them when they could look at the priests standing there motionless, with the visible symbol of God’s presence on their shoulders. The ark was no more the cause of the miracle than were its carriers; but, just as Jesus helped one blind man by laying moistened earth on his eyes, and another by sending him to Siloam to wash, so God did here. Children learn best when they have something to look at. Sight is sometimes the servant of faith.
The 12 stones preached at once the duty of remembering, and the danger of forgetting, the past mercies of God. When they were reared, they would seem needless; but the deepest impressions get filled up by degrees, as the river of time deposits its sands on them. We do not forget pain so quickly as joy, and most men have a longer and keener remembrance of their injurers than of their benefactors, human or divine. The stones were set up because Israel remembered, but also lest Israel should forget. We often think of the Jews as monsters of ingratitude; but we should more truly learn the lesson of their history, if we regarded them as fair, average men, and asked ourselves whether our recollection of God’s goodness to us is much more vivid than theirs. Unless we make distinct and frequent efforts to recall, we shall certainly forget ‘all His benefits.’ The cultivation of thankful remembrance is a very large part of practical religion; and it is not by accident that the Psalmist puts it in the middle, between hope and obedience, when he says ‘that they might set their hope in God, and not forget the works of God, but keep His commandments’
The dullest would understand what had wrought the miracle when they saw the immediate consequence of the ark’s leaving its place. Cause and effect seldom come thus close together in God’s dealings; but sometimes He lets us see them as near each other as the lightning and the thunder, that we may learn to trace them in faith, when centuries part them. How the people would gaze as the hurrying stream covered up their path, and would look across to the further shore, almost doubting if they had really stood there that morning! They were indeed ‘Hebrews’-men from the other side-now, and would set themselves to the dangerous task before them with courage. ‘Well begun is half done’; and God would not divide the river for them to thrust them into a tiger’s den, where they would be torn to pieces. Retreat was impossible now. A new page in their history was turned. The desert was as unreachable as Egypt, The passage of the Jordan rounded off the epoch which the passage of the Bed Sea introduced, and began a new era. (MacLaren)
