Numbers 18:1-2

International Standard Version

Responsibilities for Priests and Descendants of Levi

18 Later, the Lord told Aaron, “You, your sons, and your father’s tribe with you are to bear the iniquity of the sanctuary. Also, you and your sons with you are to bear the iniquity of your priesthood. ² Moreover, bring your brothers from your father’s tribe of Levi with you, so they may join you and minister to you while you and your sons with you stand in the presence of the Tent of Testimony.
