Joshua 3:15-17

and when those who carried the ark came into the Jordan, and the feet of the priests carrying the ark were dipped in the edge of the water (for the Jordan overflows all its banks all the days of harvest), the waters which were flowing down from above stood and rose up in one heap, a great distance away at Adam, the city that is beside Zarethan; and those which were flowing down toward the sea of the Arabah, the Salt Sea, were completely cut off. So the people crossed opposite Jericho. And the priests who carried the ark of the covenant of the LORD stood firm on dry ground in the middle of the Jordan while all Israel crossed on dry ground, until all the nation had finished crossing the Jordan.
