Joshua 3:14-16

So the people left the place where they had camped, and they followed the priests who carried the Ark of the Agreement across the Jordan River. During harvest the Jordan overflows its banks. When the priests carrying the Ark came to the edge of the river and stepped into the water, the water upstream stopped flowing. It stood up in a heap a great distance away at Adam, a town near Zarethan. The water flowing down to the Sea of Arabah (the Dead Sea) was completely cut off. So the people crossed the river near Jericho.
