The people marched out from their tents to cross over the Jordan. The priests carrying the covenant chest were in front of the people.
When the priests who were carrying the chest came to the Jordan, their feet touched the edge of the water. The Jordan had overflowed its banks completely, the way it does during the entire harvest season.
But at that moment the water of the Jordan coming downstream stood still. It rose up as a single heap very far off, just below Adam, which is the city next to Zarethan. The water going down to the desert sea (that is, the Dead Sea) was cut off completely. The people crossed opposite Jericho.
So the priests carrying the LORD's covenant chest stood firmly on dry land in the middle of the Jordan. Meanwhile, all Israel crossed over on dry land, until the entire nation finished crossing over the Jordan.
