Joshua 3:3-5

Young's Literal Translation

³ and command the people, saying, `When ye see the ark of the covenant of Jehovah your God, and the priests, the Levites, bearing it, then ye journey from your place, and have gone after it;

⁴ only, a distance is between you and it, about two thousand cubits by measure; ye do not come near unto it, so that ye know the way in which ye go, for ye have not passed over in the way heretofore.'

⁵ And Joshua saith unto the people, `Sanctify yourselves, for to-morrow doth Jehovah do in your midst wonders.'
