And to Aaron was born Nadab, and Abihu, Eleazar, and Ithamar.
And Aaron took Elisheba, daughter of Amminadab, sister of Naashon, as wife; and she bore him Nadab, and Abihu, Eleazar, and Ithamar.
And these are the names of the sons of Aaron; Nadab the firstborn, and Abihu, Eleazar, and Ithamar.
And they shall attend to all the instruments of the tabernacle of the congregation, and the responsibilities of the children of Israel, to do the service of the tabernacle.
