You will command the priests who are carrying the Chest of the Covenant: 'When you come to the edge of the Jordan's waters, stand there on the river bank.'"
Then Joshua addressed the People of Israel: "Attention! Listen to what God, your God, has to say.
This is how you'll know that God is alive among you - he will completely dispossess before you the Canaanites, Hittites, Hivites, Perizzites, Girgashites, Amorites, and Jebusites.
Look at what's before you: the Chest of the Covenant. Think of it - the Master of the entire earth is crossing the Jordan as you watch.
Now take twelve men from the tribes of Israel, one man from each tribe.
When the soles of the feet of the priests carrying the Chest of God, Master of all the earth, touch the Jordan's water, the flow of water will be stopped - the water coming from upstream will pile up in a heap."
And that's what happened. The people left their tents to cross the Jordan, led by the priests carrying the Chest of the Covenant.
When the priests got to the Jordan and their feet touched the water at the edge (the Jordan overflows its banks throughout the harvest),
the flow of water stopped. It piled up in a heap - a long way off - at Adam, which is near Zarethan. The river went dry all the way down to the Arabah Sea (the Salt Sea). And the people crossed, facing Jericho.
And there they stood; those priests carrying the Chest of the Covenant stood firmly planted on dry ground in the middle of the Jordan while all Israel crossed on dry ground. Finally the whole nation was across the Jordan, and not one wet foot.
