Joshua 3:4-6 American Standard Version (ASV)
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.
Joshua 3:4-6 New International Version (NIV)
4 Then you will know which way to go, since you have never been this way before. But keep a distance of about two thousand cubits[a] between you and the ark; do not go near it.”
5 Joshua told the people, “Consecrate yourselves, for tomorrow the Lord will do amazing things among you.”
6 Joshua 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.
