At Mount Sinai, Ithamar was appointed a priest over the people Israel with his father Aaron and all his brothers.
Ithamar directed the building of the materials used for the tabernacle and the tabernacle itself.
He was one of the priests of the Israelites. He served together with Aaron and Eleazar. After his two brothers Nadab and Abihu had been killed for their unauthorised offering, Ithamar and Eleazar were Aaron's only sons.
