Joshua 4:8-10

The Israelites did as Joshua commanded them. They took twelve stones according to the number of the tribes of Israel, from the middle of the riverbed, and carried them to the camp and put them there. Joshua set up the memorial stones that they had taken from the exact spot where the priests stood bearing the ark in the riverbed. They remain there to this day. While the priests remained standing in the middle of the Jordan with the ark on their shoulders, the people hurried across. All the instructions YAHWEH had given to Joshua were carried out —just as Moses had told Joshua.
