Numbers 18:3-5

New King James Version

³ They shall attend to your ^[a]needs and ^(A)all the needs of the tabernacle; ^(B)but they shall not come near the articles of the sanctuary and the altar, ^(C)lest they die—they and you also. ⁴ They shall be joined with you and attend to the needs of the tabernacle of meeting, for all the work of the tabernacle; ^(D)but an outsider shall not come near you. ⁵ And you shall attend to ^(E)the duties of the sanctuary and the duties of the altar, ^(F)that there may be no more wrath on the children of Israel.
