Joshua 4:18-24

18And it came to pass, when the priests who bore the ark of the covenant of the Lord had come from the midst of the Jordan, and the soles of the priests’ feet touched the dry land, that the waters of the Jordan returned to their place and overflowed all its banks as before.

19Now the people came up from the Jordan on the tenth day of the first month, and they camped in Gilgal on the east border of Jericho.

20And those twelve stones which they took out of the Jordan, Joshua set up in Gilgal.

21Then he spoke to the children of Israel, saying: “When your children ask their fathers in time to come, saying, ‘What are these stones?’

22then you shall let your children know, saying, ‘Israel crossed over this Jordan on dry land’;

23for the Lord your God dried up the waters of the Jordan before you until you had crossed over, as the Lord your God did to the Red Sea, which He dried up before us until we had crossed over,

24that all the peoples of the earth may know the hand of the Lord, that it is mighty, that you may fear the Lord your God forever.”
