Joshua 3:15-17

and when those who were carrying the ark came up to the Jordan, and the feet of the priests carrying the ark were submerged at the edge of the water (for the Jordan overflows all of its banks throughout the time of harvest), the waters which were flowing down from above stopped and rose up in one mass a great distance away at Adam, the city that is beside Zarethan. Those [waters] flowing downward toward the sea of the Arabah, the Salt Sea, were completely cut off. So the people crossed [the river] opposite Jericho. [Ps 114] And while all [the people of] Israel crossed over on dry ground, the priests who carried the ark of the covenant of the LORD stood firm on dry ground in the midst of the Jordan [riverbed], until all the nation had finished crossing over the Jordan.
