Joshua 4:10-12, 23

For 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. And 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. And 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

For 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
