Numbers 1:49-51 New American Bible (Revised Edition) (NABRE)
49 The tribe of Levi alone you shall not enroll nor include in the census along with the other Israelites. 50 You are to give the Levites charge of the tabernacle of the covenant with all its equipment and all that belongs to it. It is they who shall carry the tabernacle with all its equipment and who shall be its ministers; and they shall camp all around the tabernacle. 51 When the tabernacle is to move on, the Levites shall take it down; when the tabernacle is to be pitched, it is the Levites who shall set it up. Any unauthorized person who comes near[a] it shall be put to death.
