Josh 3:14-16
The people left their tents to cross the Jordan, led by the priests carrying the Chest of the Covenant. 15 When the priests got to the Jordan and their feet touched the water at the edge (the Jordan overflows its banks throughout the harvest), 16 the flow of water stopped. It piled up in a heap — a long way off — at Adam, which is near Zarethan. The river went dry all the way down to the Arabah Sea (the Salt Sea).

This is the same thing that happened at the Red Sea!
