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.
Ver. 4. Yet there shall be a space.] That you may know the distance, and show your reverence. See Exodus 19:12. As also,
That you may know the way by which you must go,] i.e., Ut ignari vice tuto vado transire possitis, that ye may have a sure and safe passage through the river discovered unto you.
