“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.

This is the inventory for the tabernacle, the tabernacle of the testimony, that was recorded at Moses’ command. It was the work of the Levites under the direction of Ithamar son of Aaron the priest.

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