Joshua 3:1-6

The next morning Joshua and all the people of Israel got up early, left the camp at Acacia, and went to the Jordan, where they camped while waiting to cross it. Three days later the leaders went through the camp and said to the people, “When you see the priests carrying the Covenant Box of the LORD your God, break camp and follow them. You have never been here before, so they will show you the way to go. But do not get near the Covenant Box; stay about a kilometre behind it.” Joshua said to the people, “Purify yourselves, because tomorrow the LORD will perform miracles among you.” Then he told the priests to take the Covenant Box and go with it ahead of the people. They did as he said.
