Nadab and Abihu died before the Lord when they brought strange fire before the Lord in the Wilderness of Sinai, and they had no children, and Eleazar and Ithamar ministered as priests in the sight of Aaron their father.
Your brothers also of the tribe of Levi, the tribe of your father, bring with you, and let them be joined with you, and minister to you. But you and your sons with you will minister before the tent of witness.
Yet they shall be ministers in My sanctuary, having charge at the gates of the house and ministering to the house. They shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister to them.
