Numbers 1:49-51

New American Standard Bible

⁴⁹ “Only the tribe of Levi ^(A)you shall not count, nor shall you take their ^[a]census among the sons of Israel. ⁵⁰ And you shall ^(B)appoint the Levites over the ^[b]tabernacle of the testimony, and over all its furnishings and over everything that belongs to it. They shall carry the tabernacle and all its furnishings, and they shall take care of it; they shall also camp around the ^[c]tabernacle. ^51 (C)So when the tabernacle is to move on, the Levites shall take it down; and when the tabernacle encamps, the Levites shall set it up. But ^(D)the ^[d]layman who comes near it shall be put to death.
