Joshua 4:18-24

And it came to pass, when the priests that bare the ark of the covenant of Jehovah were come up out of the midst of the Jordan, and the soles of the priests’ feet were lifted up unto the dry ground, that the waters of the Jordan returned unto their place, and went over all its banks, as aforetime. And the people came up out of the Jordan on the tenth day of the first month, and encamped in Gilgal, on the east border of Jericho. And those twelve stones, which they took out of the Jordan, did Joshua set up in Gilgal. And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What mean these stones? then ye shall let your children know, saying, Israel came over this Jordan on dry land. For Jehovah your God dried up the waters of the Jordan from before you, until ye were passed over, as Jehovah your God did to the Red Sea, which he dried up from before us, until we were passed over; that all the peoples of the earth may know the hand of Jehovah, that it is mighty; that ye may fear Jehovah your God for ever.
