TSK · 1 Chronicles 24:1

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

Nadab and Abihu, the sons of Aaron, each took his censer, and put fire in it, and laid incense on it, and offered strange fire before Yahweh, which he had not commanded them.

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

The children of Amram: Aaron, and Moses, and Miriam. The sons of Aaron: Nadab, and Abihu, Eleazar, and Ithamar.

David divided them into divisions according to the sons of Levi: Gershon, Kohath, and Merari.
