Ordaining the Priests

Debated

In many traditions a person entering a sacred role goes through days of ritual: bathing, new clothes, anointing, vows, a shared meal. By the end, everyone including the person themselves knows they are not who they were before. Exodus 29 lays out such a ceremony for Aaron and his sons. It is detailed, bloody and repetitive, and deliberately so. Its point is that no one simply walks into God's service; they are washed, clothed, cleansed and consecrated first.

Where it sits in the story: In Act 3, the priesthood designed in the last chapter is now given its ordination rite, which Leviticus 8 shows being carried out. The chapter ends by stating the purpose of the whole Sinai project: God will dwell among Israel and be their God. That promise runs from Eden to Revelation, and the tabernacle is one of its great milestones.

What this chapter is doing: To show how imperfect people are made fit to serve a holy God: through cleansing, sacrifice and consecration. It also establishes the daily rhythm of worship that keeps the relationship alive.

The walk-through
  • 29:1–9 — Prepare a bull, two rams and unleavened bread. Wash Aaron and his sons at the tent's entrance, dress them in the priestly garments, and anoint Aaron's head with oil. The priesthood is to be theirs as a lasting ordinance.
  • 29:10–18 — The priests lay hands on a bull offered for sin, whose remains are burned outside the camp. Then a ram is burned whole on the altar as a pleasing aroma to God, an offering of complete dedication.
  • 29:19–28 — The second ram is the ram of ordination. Its blood is put on the right ear, right thumb and right big toe of each priest: hearing, work and walk all dedicated. Portions are waved before God, and some become the priests' share.
  • 29:29–37 — The garments pass to Aaron's successors. The priests eat the ordination meal at the entrance, and the ceremony is repeated for seven days, cleansing the altar itself so it becomes most holy.
  • 29:38–46 — Every day, two lambs are offered, one in the morning and one at twilight, with flour, oil and wine. God promises to meet Israel there, to dwell among them and be their God, the God who brought them out of Egypt.
What it showsOrdination by washing, anointing and sacrifice fits priestly practices in the wider ancient Near East, and the daily morning and evening offering continued in Israel's later worship. Leviticus 8 records the ceremony being performed.
Where the evidence stopsMany scholars assign these chapters to the Priestly source and date its final form to the exile or after; traditional readers attribute them to Moses. The text's meaning is clear either way, but its date of writing is debated.

Key verse: Exodus 29:45–46  ·  So what: The end of the chapter explains the rest: all this ritual exists because God wants to live with people. The daily morning and evening offering also reminds readers that relationship with God is kept up in small, faithful repetitions, not only in dramatic moments. The letter to the Hebrews notes the burning 'outside the camp' and links it to Jesus suffering outside Jerusalem's gate.
