Joshua 3:3-6

3giving these instructions to the people: “When you see the Levitical priests carrying the Ark of the Covenant of the Lord your God, move out from your positions and follow them.

4Since you have never traveled this way before, they will guide you. Stay about half a mile behind them, keeping a clear distance between you and the Ark. Make sure you don’t come any closer.”

5Then Joshua told the people, “Purify yourselves, for tomorrow the Lord will do great wonders among you.”

6In the morning Joshua said to the priests, “Lift up the Ark of the Covenant and lead the people across the river.” And so they started out and went ahead of the people.
