Duties of Priests and Levites

18 Then the Lord said to Aaron: ^(A)“You and your sons and your father’s house with you shall ^(B)bear the ^[a]iniquity related to the sanctuary, and you and your sons with you shall bear the iniquity associated with your priesthood. ² Also bring with you your brethren of the ^(C)tribe of Levi, the tribe of your father, that they may be ^(D)joined with you and serve you while you and your sons are with you before the tabernacle of ^[b]witness.
