Ithamar

Ithamar was the youngest of Aaron's four sons by Elisheba, daughter of Amminadab, and with his brother Eleazar he became one of the two ancestors of Israel's hereditary priesthood. The text says Elisheba "bore him Nadab and Abihu, Eleazar and Ithamar" (Exodus 6:23), and Ithamar is regularly named last in the lists of Aaron's sons, as in the command to bring Aaron and his sons near to minister as priests (Exodus 28:1) and in the genealogy of Amram's line (1 Chronicles 6:3). With his father and brothers he was set apart for the priestly office at Sinai, so that his story is not that of an individual career but of a household and then a priestly house.

Scripture remembers him chiefly in two roles. First, he is a survivor. After Nadab and Abihu died before Yahweh for offering strange fire in the wilderness of Sinai, the text notes that they had no children, and that "Eleazar and Ithamar ministered in the priest's office in the presence of Aaron their father" (Numbers 3:4). Moses then instructed Aaron, Eleazar, and Ithamar not to loose their hair or tear their clothes, so that they would not die and wrath would not come on the congregation, and they were to remain at the door of the Tent of Meeting because the anointing oil was on them; "They did according to the word of Moses" (Leviticus 10:6–7). Leviticus 10:12 also shows Moses speaking to Aaron and to his two remaining sons about eating the most holy meal offering. Second, Ithamar had charge of tabernacle administration: the amounts of materials for the Tabernacle of the Testimony were counted "according to the commandment of Moses, for the service of the Levites, by the hand of Ithamar, the son of Aaron the priest" (Exodus 38:21).

Established history and the biblical record agree in placing the later organisation of the priesthood around these two surviving lines. When the priestly divisions were arranged in the days of David, the text says the sons of Aaron were "divided impartially by drawing lots," with princes of the sanctuary and princes of God from both the sons of Eleazar and the sons of Ithamar (1 Chronicles 24:5), and one fathers' house was taken for Eleazar and one for Ithamar as the scribe recorded them before the king, Zadok, Ahimelech, and the household heads (1 Chronicles 24:6). That ordering for service in Yahweh's house is described as the ordinance given to them by Aaron their father, as Yahweh had commanded him (1 Chronicles 24:19).

Christian traditions read this priestly structure with different emphases rather than disagreeing about the facts. One way to read it, common in Reformation-era and evangelical interpretation, is to treat the Aaronide priesthood, including the houses of Eleazar and Ithamar, as a provisional order fulfilled and superseded in Christ. Catholic and Orthodox teaching, by contrast, sees in the setting apart of Aaron's sons and the ordering of their service a pattern that continues in an ordained ministerial priesthood. The text itself simply narrates Ithamar as a son of Aaron who survived, served, and gave his name to a priestly house.
