Joshua 3:4
Yet there shall be a distance between you and it, a distance of about two thousand cubits by measure; do not come near it — the space between the people and the ark maintains the sacred distance appropriate to the ark's holiness and the mediated nature of access to God. The measurement emphasizes precision and careful obedience. This distance also creates a practical advantage: it allows the people to see the ark from a distance and follow its movements across the Jordan.
