Numbers 1:49-51

Revised Standard Version

⁴⁹ “Only the tribe of Levi you shall not number, and you shall not take a census of them among the people of Israel; ⁵⁰ but appoint the Levites over the tabernacle of the testimony, and over all its furnishings, and over all that belongs to it; they are to carry the tabernacle and all its furnishings, and they shall tend it, and shall encamp around the tabernacle. ⁵¹ When the tabernacle is to set out, the Levites shall take it down; and when the tabernacle is to be pitched, the Levites shall set it up. And if any one else comes near, he shall be put to death.
