Joshua 3:3-6

3giving orders to the people: “When you see the ark of the covenant of the Lord your God, and the Levitical priests carrying it, you are to move out from your positions and follow it.

4Then you will know which way to go, since you have never been this way before. But keep a distance of about two thousand cubits between you and the ark; do not go near it.”

5Joshua told the people, “Consecrate yourselves, for tomorrow the Lord will do amazing things among you.”

6Joshua said to the priests, “Take up the ark of the covenant and pass on ahead of the people.” So they took it up and went ahead of them.
