Yehoshua 3:4-6

Orthodox Jewish Bible

⁴ Yet there shall be a rachok (distance, space) between you and it, about two thousand cubits by measure; come not near unto it, that ye have da’as of the Derech by which ye must go; for ye have not passed this way heretofore.

⁵ And Yehoshua said unto HaAm, Set yourselves apart as kodesh; for tomorrow Hashem will do nifla’ot among you.

⁶ And Yehoshua spoke unto the Kohanim, saying, Take up the Aron HaBrit, and cross over before HaAm. And they took up the Aron HaBrit, and went before HaAm.
