Joshua 4:18-19

18When the priests who carried the ark of the covenant of the Lord had come up from the midst of the Jordan, and the soles of their feet were raised up to the dry land, the waters of the Jordan returned to their place, and flowed over all its banks as before.

19Now the people came up from the Jordan on the tenth [day] of the first month and encamped at Gilgal on the eastern border of Jericho.
