“And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What these stones?”
Context
18And it came to pass, when the priests that bare the ark of the covenant of the LORD were come up out of the midst of Jordan, the soles of the priests’ feet were lifted up unto the dry land, that the waters of Jordan returned unto their place, and flowed over all his banks, as before.
19And the people came up out of Jordan on the tenth of the first month, and encamped in Gilgal, in the east border of Jericho.
20And those twelve stones, which they took out of Jordan, did Joshua pitch in Gilgal.
21And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What these stones?
22Then ye shall let your children know, saying, Israel came over this Jordan on dry land.
23For the LORD your God dried up the waters of Jordan from before you, until ye were passed over, as the LORD your God did to the Red sea, which he dried up from before us, until we were gone over:
24That all the people of the earth might know the hand of the LORD, that it mighty: that ye might fear the LORD your God for ever.
