Joshua 3:14-16

So the people left their camp to cross the Jordan, and the priests who were carrying the Ark of the Covenant went ahead of them. It was the harvest season, and the Jordan was overflowing its banks. But as soon as the feet of the priests who were carrying the Ark touched the water at the river’s edge, the water above that point began backing up a great distance away at a town called Adam, which is near Zarethan. And the water below that point flowed on to the Dead Sea until the riverbed was dry. Then all the people crossed over near the town of Jericho.
