Joshua 4:11 KJV

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 everything 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 half the tribe of Manasseh, passed over armed before the children of Israel, as Moses spake unto them:

13About forty thousand prepared for war passed over before the LORD unto battle, to the plains of Jericho.
