Joshua 4:9

⁷then thou mayest explain to thy son, saying, The river Jordan was dried up from before the ark of the covenant of the Lord of the whole earth, when it passed it: and these stones shall be for a memorial for you for the children of Israel forever.

⁸And the children of Israel did so, as the Lord commanded Joshua; and they took up twelve stones out of the midst of Jordan (as the Lord commanded Joshua, when the children of Israel had completely passed over), and carried these stones with them into the camp, and laid them down there.

— Joshua 4:9 —

¹⁰And the priests that bore the ark of the covenant stood in Jordan, until Joshua had finished all that the Lord commanded him to report to the people; and the people hastened and passed over.

¹¹And it came to pass when all the people had passed over, that the ark of the covenant of the Lord passed over, and the stones before them.
