Joshua 3:3-6

3and they commanded the people, saying, “When you see the 1ark 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. 4However, there shall be between you and it a distance of about 2,000 2cubits by measure. Do not come near it, that you may know the way by which you shall go, for you have not passed this way before.”

5Then Joshua said to the people, “3Consecrate yourselves, for tomorrow the Lord will do wonders among you.” 6And 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.
