Joshua 4:19-22

The people came up out of the Jordan on the tenth day of the first month. They set up camp at The Gilgal (The Circle) to the east of Jericho. Joshua erected a monument at The Gilgal, using the twelve stones that they had taken from the Jordan. And then he told the People of Israel, “In the days to come, when your children ask their fathers, ‘What are these stones doing here?’ tell your children this: ‘Israel crossed over this Jordan on dry ground.’
