Joshua 3:4-6

American Standard Version

⁴ Yet 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. ⁵ And Joshua said unto the people, Sanctify yourselves; for to-morrow Jehovah will do wonders among you. ⁶ And 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.
