Numbers 1:49-51

New Revised Standard Version, Anglicised Catholic Edition

⁴⁹ Only the tribe of Levi you shall not enrol, and you shall not take a census of them with the other Israelites. ⁵⁰ Rather you shall appoint the Levites over the tabernacle of the covenant,^[a] and over all its equipment, and over all that belongs to it; they are to carry the tabernacle and all its equipment, and they shall tend it, and shall camp 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 any outsider who comes near shall be put to death.
