1 Chronicles 6:50

And Aaron took him Elisheba, daughter of Amminadab, sister of Naashon, to wife; and she bare him Nadab, and Abihu, Eleazar, and Ithamar.

And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, even Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.

And Moses diligently sought the goat of the sin offering, and, behold, it was burnt: and he was angry with Eleazar and Ithamar, the sons of Aaron which were left alive, saying,

And Nadab and Abihu died before the LORD, when they offered strange fire before the LORD, in the wilderness of Sinai, and they had no children: and Eleazar and Ithamar ministered in the priest's office in the sight of Aaron their father.

And strip Aaron of his garments, and put them upon Eleazar his son: and Aaron shall be gathered unto his people, and shall die there. And Moses did as the LORD commanded: and they went up into mount Hor in the sight of all the congregation. And Moses stripped Aaron of his garments, and put them upon Eleazar his son; and Aaron died there in the top of the mount: and Moses and Eleazar came down from the mount.

And Moses did as the LORD commanded him: and he took Joshua, and set him before Eleazar the priest, and before all the congregation:

And the children of Amram; Aaron, and Moses, and Miriam. The sons also of Aaron; Nadab, and Abihu, Eleazar, and Ithamar. Eleazar begat Phinehas, Phinehas begat Abishua, And Abishua begat Bukki, and Bukki begat Uzzi, And Uzzi begat Zerahiah, and Zerahiah begat Meraioth, Meraioth begat Amariah, and Amariah begat Ahitub, And Ahitub begat Zadok, and Zadok begat Ahimaaz, And Ahimaaz begat Azariah, and Azariah begat Johanan,

Now these are the divisions of the sons of Aaron. The sons of Aaron; Nadab, and Abihu, Eleazar, and Ithamar.
