Aaron

Leaders of Israel · Around 1300 BC (traditional) · Appears in Exodus through Deuteronomy

Aaron is the elder brother of Moses and the first high priest of Israel. He was Moses' spokesman before Pharaoh and the one appointed by God to offer sacrifice and to bless the people. His life holds both high honor, in the priesthood, and deep failure, in the making of the golden calf.

The LORD bless thee, and keep thee:Numbers 6:24 (KJV)

The voice for his brother

When Moses stood at the burning bush and protested that he was slow of speech and could not go before Pharaoh, God's anger was kindled, but he provided a helper: Aaron, Moses' elder brother, who could speak well. God said Aaron would be as a mouth to Moses, and Moses as God to Aaron. So the two brothers, long separated, met again in the wilderness and went together to face the most powerful ruler on earth with a word from a God the Egyptians did not know.

Through the contest with Pharaoh, Aaron stood at his brother's side. It was Aaron's rod that became a serpent and swallowed the rods of the magicians, and Aaron's rod that was stretched out over the waters of Egypt to begin the plagues. When Israel fought Amalek in the wilderness, it was Aaron and Hur who held up the weary arms of Moses so that Israel prevailed. From the beginning Aaron's calling was to support, to speak, and to stand alongside the leader God had chosen.

The golden calf

Aaron's darkest hour came at the foot of Sinai. While Moses was up on the mountain with God for forty days, the people grew restless and pressed Aaron to make them gods to go before them. Instead of resisting, Aaron gave way. He gathered their gold, fashioned it into a molten calf, built an altar before it, and proclaimed a feast, and the people rose up to play in idolatry and revelry. It was a grievous sin at the very moment God was giving the covenant above them.

When Moses came down and confronted him, Aaron offered a weak and evasive excuse, saying he had thrown the gold into the fire and out came this calf, as though it had made itself. It is a painfully honest picture of a leader who could not stand against the crowd. Yet the wonder of the story is that God did not cast Aaron off. Grace ran deeper than his failure, and the man who made the golden calf would still be called to lead the people to the true God.

The first high priest

God called Aaron and his sons to the priesthood, an office of astonishing privilege. Moses clothed Aaron in the holy garments: the breastplate set with twelve stones for the twelve tribes, the ephod, the robe, and the golden plate on his forehead engraved Holiness to the LORD. Anointed with oil and consecrated with sacrifice, Aaron became the first high priest of Israel, the one man who could enter the Most Holy Place, and then only once a year on the Day of Atonement, carrying the blood that made atonement for the sins of the whole people.

When some challenged whether Aaron's family alone should serve as priests, God settled it by a sign: of all the tribal rods laid up before him, only Aaron's budded, blossomed, and bore ripe almonds overnight, showing that the LORD had chosen him. To Aaron and his sons God gave the great blessing to speak over Israel, The LORD bless thee, and keep thee; the LORD make his face shine upon thee, words still spoken over God's people today. Aaron served until his death on Mount Hor, where his priestly garments were passed to his son Eleazar.

The weight of holy service

The priesthood was a place of honor, but it was also a place of awesome responsibility, and Aaron learned its weight in the hardest way. On the very day the priesthood began, his two elder sons, Nadab and Abihu, offered strange fire before the LORD which he had not commanded, and fire went out from the LORD and consumed them. Moses told Aaron that God would be sanctified in those who came near him, and Aaron held his peace, silent in his grief before the holiness of God.

The lesson was that God is not approached carelessly or on human terms, but only in the way he has appointed. Aaron carried that trust every day, bearing the names of the tribes over his heart, and once a year passing alone through the veil into the Most Holy Place, not without blood, to make atonement for the people. The whole ministry taught Israel to reverence a holy God and to long for a mediator who could bring them near without fear, a longing that Scripture would answer in one far greater than Aaron.

His character and significance

Aaron is a study in a man of real gifts and real weakness. He was eloquent where Moses was slow, a natural spokesman and a leader the people looked to, and he shared in the great works of the Exodus. But he could be swayed by the crowd, as the golden calf showed, and he once joined his sister Miriam in jealousy against Moses. He is neither hero nor villain but a flawed man lifted to holy office, a reminder that God works through people who need the very forgiveness they help others find.

His lasting significance is the priesthood he founded, which stood at the center of Israel's worship for centuries. Through Aaron and his line, the people learned that a holy God could be approached only through appointed sacrifice and a mediator, that sin must be atoned for by blood, and that God had made a way for guilty people to draw near. That whole system of altar, blood, and mediation taught Israel to long for a cleansing it could picture but never finally achieve.

Where Aaron points to Christ

The book of Hebrews sets Aaron's priesthood beside the priesthood of Jesus and shows how far the shadow falls short of the substance. Aaron had to offer sacrifice first for his own sins before he could offer for the people, and he offered the blood of animals year after year, blood that could never truly take sin away. He died, and his office had to pass to another. He was a mediator who himself needed a mediator.

Jesus is the great high priest of a better covenant, holy, harmless, and undefiled, who needed no sacrifice for himself, and who offered not the blood of bulls and goats but his own blood, once for all. He did not enter a tabernacle made with hands but heaven itself, and he lives forever to make intercession for those who come to God through him. Aaron pointed toward a priest who could truly bring us home, and that priest is Christ, not after the fading order of Aaron but forever after the order of Melchizedek.

A note on the sources: everything above is drawn from the biblical text itself. Where a detail comes from later tradition rather than Scripture, it is named as tradition. Dates for the earliest figures are traditional and approximate, and Scripture does not always give them. The aim is to tell each life honestly, and to let it do what the whole Bible does, point to Jesus Christ the Lord.
