Joshua 4:4-13

4Then Joshua called the twelve men whom he had appointed from the children of Israel, one man from every tribe;

5and Joshua said to them: “Cross over before the ark of the Lord your God into the midst of the Jordan, and each one of you take up a stone on his shoulder, according to the number of the tribes of the children of Israel,

6that this may be a sign among you when your children ask in time to come, saying, ‘What do these stones mean to you?’

7Then you shall answer them that the waters of the Jordan were cut off before the ark of the covenant of the Lord; when it crossed over the Jordan, the waters of the Jordan were cut off. And these stones shall be for a memorial to the children of Israel forever.”

8And the children of Israel did so, just as Joshua commanded, and took up twelve stones from the midst of the Jordan, as the Lord had spoken to Joshua, according to the number of the tribes of the children of Israel, and carried them over with them to the place where they lodged, and laid them down there.

9Then Joshua set up twelve stones in the midst of the Jordan, in the place where the feet of the priests who bore the ark of the covenant stood; and they are there to this day.

10So the priests who bore the ark stood in the midst of the Jordan until everything was finished that the Lord had commanded Joshua to speak to the people, according to all that Moses had commanded Joshua; and the people hurried and crossed over.

11Then it came to pass, when all the people had completely crossed over, that the ark of the Lord and the priests crossed over in the presence of the people.

12And the men of Reuben, the men of Gad, and half the tribe of Manasseh crossed over armed before the children of Israel, as Moses had spoken to them.

13About forty thousand prepared for war crossed over before the Lord for battle, to the plains of Jericho.
