Joshua 4:9-10

9Joshua also made a heap of 12 stones in the middle of the Jordan River. He put them in the place where the priests with the Covenant Box had stood. Those stones are still there today.

10The priests had carried the Covenant Box into the middle of the river. They stood there while the people did everything that the Lord had told Joshua. That is what Moses had also told Joshua. The people crossed over the river quickly.
