Biblical Profile: Aaron

Aaron

Moses’ older brother, Aaron (see Exod 6:20; 7:7), played a crucial role in founding Israel and its institutions, particularly the priesthood. He first appears after Moses’ calling at the burning bush (Exod 3:1–4:17). Moses was reluctant to accept his divine commission, claiming that he was unfit to lead the Israelites out of Egypt because his words tended to “get tangled” (Exod 4:10). Despite God’s assurances, Moses continued to object until God appointed Aaron to be Moses’ mouthpiece. Thereafter, Aaron was often at Moses’ side, speaking to the Israelite leaders and demanding that Pharaoh let the Israelites leave Egypt (Exod 5:1-5).

During the Israelites’ wilderness wanderings, God appointed Aaron and his sons to be set apart and dedicated as priests (Exod 28:1-5; 29:1-46; Lev 8:1-36). Thus, Aaron became Israel’s first high priest. Aaron’s role as high priest was especially prominent on the annual Day of Atonement, the only day when the high priest entered the Most Holy Place to purify it from the effects of Israel’s sins (Lev 16). Before the high priest could do so, however, he had to offer a sacrifice to atone for his own sins.

Aaron was an imperfect leader. While Moses was on Mount Sinai receiving the law from God, Aaron helped the people make an idol (Exod 32). When Moses returned, Aaron gave poor excuses and blamed the people. This event resulted in the death of three thousand Israelites, as well as a plague.

Aaron and his sister, Miriam, once wrongly challenged Moses’ authority, resulting in a temporary state of leprosy for Miriam (Num 12). Later, when other Levites challenged Aaron’s authority, God affirmed Aaron’s role by making his staff bud with almond blossoms (Num 17). However, because Moses and Aaron challenged God’s authority (Num 20:1-13), they both died in the wilderness without entering the Promised Land (Num 20:22-29).

Jesus has become the Great High Priest, far surpassing Aaron’s priestly authority and effectiveness (see Heb 7–10).
