אַהֲרוֹן
Aharon, the brother of Moses
Definition
אַהֲרוֹן (Aaron) is the name of the brother of Moses and the first high priest of Israel. He served as Moses' spokesperson before Pharaoh (Exodus 4:14-16) and became the founding figure of the Israelite priesthood, an office later confirmed for his descendants (Exodus 28:1). His role encompassed both leading Israel in worship and, at times, failing in leadership, as seen in the incident of the golden calf (Exodus 32:1-5) and the rebellion at Meribah (Numbers 20:1-13). The name 'Aaron' is used exclusively for this individual throughout the Old Testament.
Biblical Usage
The name appears 328 times, primarily in the Torah (Exodus, Leviticus, Numbers) and Psalms, detailing his life, priestly duties, and lineage. It is used in narratives of Israel's exodus and wilderness journey, in legal texts establishing the priesthood (Leviticus 8-9), and in genealogical records (1 Chronicles 6:3-15, 23:13). Later prophetic books reference him as the archetypal priest (Micah 6:4). The usage consistently identifies him in relation to Moses, the priesthood, and the tribe of Levi.
Etymology
The etymology of אַהֲרוֹן is uncertain. Proposed origins include Egyptian, possibly meaning 'warrior lion,' or derived from Hebrew roots related to 'ark' or 'mountain.' Some connect it to the Hebrew word for 'to sing' or 'to shine.' Its exact derivation remains unclear, but its significance is defined entirely by its biblical narrative context rather than a transparent Hebrew root.
Semantic Range
Aaron is central to the theology of priesthood, mediation, and atonement in the Old Testament. His anointing (Leviticus 8:12) establishes a pattern for consecrated service to God, and his role in offering sacrifices prefigures the ultimate High Priest, Jesus Christ (Hebrews 5:1-5, 9:11-14). His failures highlight human frailty even in sacred office, while God's enduring covenant with his line (Numbers 25:10-13) underscores divine grace and the importance of intercession.
In ancient Israelite culture, Aaron's establishment as high priest created a hereditary, sacred office central to national identity and worship. The high priest was the sole mediator allowed to enter the Most Holy Place on the Day of Atonement (Leviticus 16), representing the people before God. This role carried immense social, religious, and political authority, setting the Aaronic priesthood apart from other ancient Near Eastern priestly systems which were often tied to specific temples or monarchs.
כֹּהֵן (kōhēn, H3548) — The generic term for 'priest'; Aaron was the first and chief כֹּהֵן. לֵוִי (Lēwî, H3878) — Denotes his tribal lineage; Aaron was a Levite, but his priestly office was a specific calling within that tribe.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
