And Nadab and Abihu died before LORD when they offered strange fire before LORD in the wilderness of Sinai, and they had no sons. And Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father.
And thy brothers also, the tribe of Levi, the tribe of thy father, bring thou near with thee, that they may be joined to thee, and minister to thee, but thou and thy sons with thee shall be before the tent of the testimony.
Yet they shall be ministers in my sanctuary, having oversight at the gates of the house, and ministering in the house. They shall kill the burnt-offering and the sacrifice for the people, and they shall stand before them to ministe
And Aaron shall offer the Levites before LORD for a wave-offering on the behalf of the sons of Israel, that it may be theirs to do the service of LORD.
