Joshua 3:3-8

3and they commanded the people, saying, When ye see the ark of the covenant of the LORD your God, and the priests the Levites bearing it, then ye shall remove from your place, and go after it.

4Yet there shall be a space between you and it, about two thousand cubits by measure: come not near unto it, that ye may know the way by which ye must go; for ye have not passed this way heretofore.

5And Joshua said unto the people, Sanctify yourselves: for tomorrow the LORD will do wonders among you.

6And Joshua spake unto the priests, saying, Take up the ark of the covenant, and pass over before the people. And they took up the ark of the covenant, and went before the people.

7And the LORD said unto Joshua, This day will I begin to magnify thee in the sight of all Israel, that they may know that as I was with Moses, so I will be with thee.

8And thou shalt command the priests that bear the ark of the covenant, saying, When ye are come to the brink of the waters of Jordan, ye shall stand still in Jordan.
