Joshua 3:3-7

and they commanded the people, saying, “When you see the ark of the covenant of the Lord your God with the Levitical priests carrying it, then you shall set out from your place and go after it.

However, there shall be a distance between you and it of about two thousand cubits by measurement. Do not come near it, so that you may know the way by which you shall go, for you have not passed this way before.”

Then Joshua said to the people, “Consecrate yourselves, for tomorrow the Lord will do miracles among you.”

And Joshua spoke to the priests, saying, “Take up the ark of the covenant and cross over ahead of the people.” So they took up the ark of the covenant and went ahead of the people.

Now the Lord said to Joshua, “This day I will begin to exalt you in the sight of all Israel, so that they will know that just as I have been with Moses, I will be with you.
