Joshua 4:4-13

4Then Joshua called the twelve men, whom he had prepared of the children of Israel, out of every tribe a man:

5and Joshua said unto them, Pass over before the ark of the LORD your God into the midst of Jordan, and take you up every man of you a stone upon his shoulder, according unto the number of the tribes of the children of Israel:

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

7then ye shall say unto them, Because the waters of Jordan were cut off before the ark of the covenant of the LORD; when it passed over Jordan, the waters of Jordan were cut off: and these stones shall be for a memorial unto the children of Israel for ever.

8And the children of Israel did so as Joshua commanded, and took up twelve stones out of the midst of Jordan, as the LORD spake unto Joshua, according to the number of the tribes of the children of Israel; and they carried them over with them unto the place where they lodged, and laid them down there.

9And Joshua set up twelve stones in the midst of Jordan, in the place where the feet of the priests which bare the ark of the covenant stood: and they are there, unto this day.

10For the priests which bare the ark stood in the midst of Jordan, until every thing was finished that the LORD commanded Joshua to speak unto the people, according to all that Moses commanded Joshua: and the people hasted and passed over.

11And it came to pass, when all the people were clean passed over, that the ark of the LORD passed over, and the priests, in the presence of the people.

12And the children of Reuben, and the children of Gad, and the half tribe of Manasseh, passed over armed before the children of Israel, as Moses spake unto them:

13about forty thousand ready armed for war passed over before the LORD unto battle, to the plains of Jericho.
