Aaron married Elisheba, daughter of Amminadab and sister of Nahshon. She bore him Nadab and Abihu, Eleazar and Ithamar.

Then He said to Moses, "Go up to the Lord, you and Aaron, Nadab, and Abihu, and 70 of Israel's elders, and bow in worship at a distance.

Then Moses went up with Aaron, Nadab, and Abihu, and 70 of Israel's elders,

"Have your brother Aaron, with his sons, come to you from the Israelites to serve Me as priest-Aaron, his sons Nadab and Abihu, Eleazar and Ithamar.

Aaron's sons Nadab and Abihu each took his own firepan, put fire in it, placed incense on it, and presented unauthorized fire before the Lord, which He had not commanded them [to do]. Then flames leaped from the Lord's presence and burned them to death before the Lord.

These are the names of Aaron's sons: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.

But Nadab and Abihu died in the Lord's presence when they presented unauthorized fire before the Lord in the Wilderness of Sinai, and they had no sons. So Eleazar and Ithamar served as priests under the direction of Aaron their father.

Nadab, Abihu, Eleazar, and Ithamar were born to Aaron, but Nadab and Abihu died when they presented unauthorized fire before the Lord.
