Joshua 4:19-24

19On the tenth day of the first month the people went up from the Jordan and camped at Gilgal on the eastern border of Jericho.

20And Joshua set up at Gilgal the twelve stones they had taken out of the Jordan.

21He said to the Israelites, “In the future when your descendants ask their parents, ‘What do these stones mean?’

22tell them, ‘Israel crossed the Jordan on dry ground.’

23For the Lord your God dried up the Jordan before you until you had crossed over. The Lord your God did to the Jordan what he had done to the Red Sea when he dried it up before us until we had crossed over.

24He did this so that all the peoples of the earth might know that the hand of the Lord is powerful and so that you might always fear the Lord your God.”
