28 “You are to summon from the Israelites your brother Aaron, along with his sons, so that he may serve as priest to me+—Aaron,+ along with Naʹdab and A·biʹhu,+ El·e·aʹzar and Ithʹa·mar,+ the sons of Aaron.+

10 You should appoint Aaron and his sons, and they are to carry out their priestly duties,+ and any unauthorized person* who comes near should be put to death.”+

8 “At that time Jehovah set apart the tribe of Leʹvi+ to carry the ark of Jehovah’s covenant,+ to stand before Jehovah in order to minister to him, and to bless in his name,+ as they do to this day.
