According to the
Book of Exodus, Aaron first functioned as
Moses' assistant. Because Moses complained that he could not speak well, God appointed Aaron as Moses' "prophet". Then he stretched out his
rod in order to bring on the first three plagues. After that, Moses tended to act and speak for himself. During the journey in the wilderness, Aaron was not always prominent or active. At the
battle with Amalek, he was chosen with
Hur to support the hand of Moses that held the "
rod of God". When the revelation was given to Moses at
Mount Sinai, he headed the elders of Israel who accompanied Moses on the way to the summit. While
Joshua went with Moses to the top, however, Aaron and Hur remained below to look after the people. From here on in Exodus, Leviticus and Numbers, Joshua appears in the role of Moses' assistant while Aaron functions instead as the first high priest.
High Priest The books of
Exodus,
Leviticus and
Numbers maintain that Aaron received from God a monopoly over the priesthood for himself and his male descendants. The family of Aaron had the exclusive right and responsibility to make offerings on the altar to
Yahweh. The rest of his tribe, the
Levites, were given subordinate responsibilities within the sanctuary. Moses anointed and consecrated Aaron and his sons to the priesthood, and arrayed them in the robes of office. He also related to them God's detailed instructions for performing their duties while the rest of the Israelites listened. Aaron and his successors as high priest were given control over the
Urim and Thummim by which the will of God could be determined. God commissioned the Aaronide priests to distinguish the holy from the common and the clean from the unclean, and to teach the divine laws (the
Torah) to the Israelites. The priests were also commissioned to bless the people. When Aaron completed the altar offerings for the first time and, with Moses, "blessed the people: and the glory of the appeared unto all the people: And there came a fire out from before the , and consumed upon the altar the burnt offering and the fat [which] when all the people saw, they shouted, and fell on their faces". In this way, the institution of the Aaronide priesthood was established. In later books of the Hebrew Bible, Aaron and his kin are not mentioned very often except in literature dating to the
Babylonian captivity and later. The books of
Judges,
Samuel and
Kings mention priests and Levites, but do not mention the Aaronides in particular. The
Book of Ezekiel, which devotes much attention to priestly matters, calls the priestly upper class the
Zadokites after one of King David's priests. Most scholars think the Torah reached its final form early in this period, which may account for Aaron's prominence in Exodus, Leviticus and Numbers.
Conflicts Aaron plays a leading role in several stories of conflicts during Israel's wilderness wanderings. During the prolonged absence of Moses on Mount Sinai, the people provoked Aaron to make a
golden calf. This incident nearly caused God to destroy the Israelites. Moses successfully intervened, but then led the loyal Levites in executing many of the culprits; a plague afflicted those who were left. Aaron, however, escaped punishment for his role in the affair, because of the intercession of Moses according to Deuteronomy 9:20. Later retellings of this story almost always excuse Aaron for his role. For example, in rabbinic sources and in the Quran, Aaron was not the idol-maker and upon Moses' return begged his pardon because he felt mortally threatened by the Israelites. On the day of Aaron's consecration, his oldest sons,
Nadab and Abihu, were burned up by divine fire because they offered "strange" incense. Most interpreters think this story reflects a conflict between priestly families some time in Israel's past. Others argue that the story simply shows what can happen if the priests do not follow God's instructions given through Moses. Numbers 12, however, reports that on one occasion, Aaron and Miriam complained about Moses' exclusive claim to be the Lord's prophet. Their presumption was rebuffed by God who affirmed Moses' uniqueness as the one with whom the Lord spoke face to face. Miriam was punished with a skin disease (
tzaraath) that turned her skin white. Aaron pleaded with Moses to intercede for her, and Miriam, after seven days' quarantine, was healed. Aaron once again escaped any retribution. According to Numbers 16–17, a Levite named
Korah led many in challenging Aaron's exclusive claim to the priesthood. When the rebels were punished by being swallowed up by the earth,
Eleazar, the son of Aaron, was commissioned to take charge of the
censers of the dead priests. And when a plague broke out among the people who had sympathized with the rebels, Aaron, at the command of Moses, took his censer and stood between the living and the dead until the plague abated (Numbers 16:36, 17:1), atoning in the process. To emphasize the validity of the Levites' claim to the offerings and tithes of the Israelites, Moses collected a rod from the leaders of each tribe in Israel and laid the twelve rods overnight in the
tent of meeting. The next morning, Aaron's rod was found to have budded and blossomed and produced ripe almonds. The rod was then placed before the
Ark of the Covenant to symbolize Aaron's right to priesthood. The following chapter then details the distinction between Aaron's family and the rest of the Levites: while all the Levites (and only Levites) were devoted to the care of the sanctuary, charge of its interior and the altar was committed to the
Aaronites alone.
Death Aaron, like Moses, was not permitted to enter Canaan with the Israelites There are two accounts of the death of Aaron in the Torah. The other account is found in Deuteronomy 10:6, where Aaron died at Moserah and was buried. There is a significant amount of travel between these two points, as the itinerary in Numbers 33:31–37 records seven stages between Moseroth (Mosera) and Mount Hor. Aaron died on the 1st of
Av and was 123 at the time of his death. The sons of Aaron were
Nadab,
Abihu,
Eleazar and
Ithamar; only the latter two had progeny. A descendant of Aaron is an Aaronite, or
Kohen, meaning Priest. Any non-Aaronic
Levite—i.e., descended from Levi but not from Aaron—assisted the Levitical priests of the family of Aaron in the care of the tabernacle; later of the temple. The
Gospel of Luke records that both
Zechariah and
Elizabeth and therefore their son
John the Baptist were descendants of Aaron.
