Numbers 18:1-2

Complete Jewish Bible

18 Adonai said to Aharon, “You, your sons and your father’s family line will be responsible for anything that goes wrong in the sanctuary. You and your sons with you will be responsible for anything wrong in your service as cohanim. ² But you are to bring your kinsmen, the tribe of Levi, along with yourselves, to work together with you and help you — you and your sons with you — when you are there before the tent of meeting.
