That the waters which came down from above stood and rose up upon an heap very far from the city Adam, that is beside Zaretan: and those that came down toward the sea of the plain, even the salt sea, failed, and were cut off: and the people passed over right against Jericho. Rose up upon a heap - That is, they continued to accumulate, filling up the whole of the channel toward the source, and the adjacent ground over which they were now spread, to a much greater depth, the power of God giving a contrary direction to the current. We need not suppose them to be gathered up like a mountain, instar montis, as the Vulgate expresses it, but that they continued to flow back in the course of the channel; and ere they could have reached the lake of Gennesareth, where they might have been easily accumulated, the whole Israelitish army would have all got safely to the opposite side.
Very far from the city Adam - beside Zaretan - Where these places were it is difficult to say. The city Adam is wholly unknown. From 1 Kings 4:12 we learn that Zartanah was below Jezreel near Bethshean, or Scythopolis, and not far from Succoth, 1 Kings 7:46. And it appears from Genesis 33:17, Joshua 13:27, that Succoth lay on the east side of Jordan, not far from the lake of Gennesareth; and probably Adam was on the same side to the north of Succoth. It is probable that the Israelites crossed the Jordan near Bethabara, where John baptized, John 1:28, and which probably had its name, the house of passage, from this very circumstance. After all, it is extremely difficult to ascertain the exact situation of these places, as in the lapse of upwards of 3,000 years the face of the country must have been materially changed. Seas, rivers, and mountains, change not; and though we cannot ascertain the spot, it is sufficiently evident that we can come near to the place. It has been considered a lame objection against the truth of the Iliad that the situation of Troy cannot now be exactly ascertained. There are even many ancient cities and considerable towns in Europe, that, though they still bear their former names, do not occupy the same spot. There are not a few of those even in England; among such Norwich, Salisbury, etc., may be ranked, neither of which is in its primitive situation.
Right against Jericho - It would be impossible for the whole camp to pass over in the space opposite to Jericho, as they must have taken up some miles in breadth, besides the 2,000 cubits which were left on the right between them and the ark; but the river was divided opposite to Jericho, and there the camp began to pass over.
