Joshua 3:12-16

12 Now choose twelve men, one from each of the tribes of Israel.
13 When the priests who carry the Covenant Box of the Lord of all the earth put their feet in the water, the Jordan will stop flowing, and the water coming downstream will pile up in one place."
14 It was harvest time, and the river was in flood. When the people left the camp to cross the Jordan, the priests went ahead of them, carrying the Covenant Box. As soon as the priests stepped into the river,
16 the water stopped flowing and piled up, far upstream at Adam, the city beside Zarethan. The flow downstream to the Dead Sea was completely cut off, and the people were able to cross over near Jericho.
