And Aaron took Elisheba, the daughter of Amminadab, sister of Nahshon, for his wife. And she bore him Nadab and Abihu, Eleazar and Ithamar.

And Aaron's son Eleazar took his wife of the daughters of Putiel. And she bore him Phinehas. These were the heads of the fathers of the Levites according to their families.

And you shall take to yourself Aaron your brother, and his sons with him, from among the sons of Israel, so that he may minister to Me in the priest's office: Aaron and Aaron's sons, Nadab and Abihu, Eleazar and Ithamar.
