Conditional birth estimate
Conditional birth bounds under generation assumptions; not attested parental ages, biological limits or a lifespan.
The anchors give incompatible conditional intervals. This calculation establishes no birth year.
Below are relatives with a selected birth year, the generations separating them, and the interval allowed by each anchor. Each relative’s page shows available dates and sources. The overall estimate uses the intersection of the allowed intervals.

Ithamar was the fourth and youngest son of Aaron, the first high priest of Israel (Exo 6:23). He served as a priest alongside his brothers Nadab, Abihu, and Eleazar (Num 3:2). After the deaths of Nadab and Abihu for offering unauthorized fire before the Lord (Lev 10:1-2), Ithamar and Eleazar were warned not to mourn for them openly (Lev 10:6).
Ithamar assisted his father Aaron and his brother Eleazar in their priestly duties (Exo 28:1; Num 3:4). He was responsible for overseeing the Gershonites and Merarites, two of the Levite clans, in their tabernacle duties (Num.4.28,33). During the dedication of the tabernacle, Ithamar assisted Moses in receiving the offerings from the tribal leaders (Num 7:8).
Ithamar's descendants continued to serve as priests (1Ch 24:1-6). They were divided into divisions for their appointed duties, just as Aaron's other descendants were. One of Ithamar's notable descendants was Eli, who served as high priest and judge in Israel (1Sa 14:3; 1Ki 2:27).
In Ezr 8:2, a descendant of Ithamar named Daniel is mentioned among the priests who returned to Jerusalem from the Babylonian exile. This highlights the continuity of Ithamar's lineage in the priesthood.
Palm isle, the fourth and youngest son of Aaron (1 Chr. 6:3). He was consecrated to the priesthood along with his brothers (Ex. 6:23); and after the death of Nadab and Abihu, he and Eleazar alone discharged the functions of that office (Lev. 10:6, 12; Num. 3:4). He and his family occupied the position of common priest till the high priesthood passed into his family in the person of Eli (1 Kings 2:27), the reasons for which are not recorded.
