Joshua 4:10-12, 23

For the priests bearing the ark stood in the midst of the Jordan until everything was finished that the LORD commanded Joshua to tell the people, according to all that Moses had commanded Joshua. The people passed over in haste. And when all the people had finished passing over, the ark of the LORD and the priests passed over before the people. The sons of Reuben and the sons of Gad and the half-tribe of Manasseh passed over armed before the people of Israel, as Moses had told them.

For the LORD your God dried up the waters of the Jordan for you until you passed over, as the LORD your God did to the Red Sea, which he dried up for us until we passed over
