ITHAMAR (ĭth'a-mar, Heb. ’îthāmār). The youngest of the four sons of Aaron, the others being Eleazar, Nadab, and Abihu. Aaron and his sons were consecrated to the priesthood (Exod.28.1), but Nadab and Abihu were put to death for offering unauthorized fire (Lev.10.1-Lev.10.20). During the wilderness wanderings he was the treasurer of the offerings for the tabernacle (Exod.38.21) and superintendent of the Gershonites and Merarites (Num.4.28, Num.4.33). He founded the priestly family to which Eli and his descendants belonged, and this continued after the Captivity (1Chr.24.4-1Chr.24.6; Ezra.8.2).
During the wilderness wanderings he was leader over all the Levites (Exod 38:21), over the Gershonites (Num 4:28), and over the Merarites (4:33, 7:8). He founded a priestly family, to which Eli and his descendants belonged (1 Chron 24:4-6). According to Ezra 8:2 the family of Ithamar continued after the captivity.
