Consecration of the Priests

Study notes

The consecration rites for Aaron and his sons combine washing, layered garments, and successive offerings to render both the men and the altar fit for service. Blood from the sin offering and the ram of setting is applied to the altar horns and to the priests’ ears, thumbs, and toes, while selected portions ascend in fire and the remainder is eaten only by those ordained. Seven days of repetition purify the altar until it becomes most holy, after which two lambs offered each morning and evening sustain the entrance of the tent of meeting as the site where the LORD meets Israel and dwells in their midst.

What is Consecration of the Priests about?

The instructions open with the animals and bread required to consecrate Aaron and his sons so they can minister before the LORD. One bull from the herd, two unblemished rams, and loaves and wafers made of fine wheat flour mixed with oil are gathered and brought to the entrance of the tent of meeting. There the men are washed, dressed in the garments already described, and anointed with oil.

The central question is how these particular men are to be made fit for service at the altar. The procedure combines washing, clothing, blood applied to ear, thumb, and toe, and the burning of specific portions so that the priests and the altar itself become set apart. Aaron and his sons lay their hands on the heads of the animals, identifying themselves with the offerings that remove what would otherwise bar them from approach.

These verses matter right after the account of the garments because clothing alone does not create priests. The ritual actions that follow turn the men into those who can handle the daily lambs, the grain, and the drink offerings that keep the tent of meeting as the place where the LORD meets Israel.

Where does this passage sit in Exodus?

The instructions for consecrating Aaron and his sons stand immediately after the completed description of their garments. Chapter 28 had ended by listing the tunics, sashes, and headgear for the sons alongside the more elaborate vestments for Aaron. The opening command of chapter 29 therefore takes those same garments up again and directs that they be placed on the men at the entrance of the tent of meeting. The transition moves from pattern to performance.

Within the larger sequence of tabernacle instructions that runs from chapter 25 through chapter 31, this chapter supplies the missing personnel. The altar, the lampstand, the table, and the tent itself have already been described; now the men who will serve at them receive the rites that set them apart. The repeated requirement that the ordination last seven days echoes the seven-day pattern already used for the consecration of the altar itself later in the same chapter, binding priests and altar together under one statute.

The chapter also prepares for what follows. Once the priests are ordained, the text turns at once to the daily burnt offerings that will be offered at the same entrance where the ordination took place. That daily rhythm, described in verses 38–42, extends the single event of consecration into the ongoing life of the sanctuary. Later, when the tabernacle is finally erected in chapter 40, the same sequence of washing, clothing, anointing, and sacrifice is carried out, showing that the directions given here are not an appendix but the necessary bridge between the finished structure and its actual use.

How is the passage structured?

The instructions begin with a compact list of materials in verses 1-3: one bull, two rams, and three kinds of unleavened bread placed together in a single basket. The next block, verses 4-9, shifts to the men themselves. Aaron and his sons are brought forward, washed, dressed in layered garments, and Aaron alone is anointed with oil. The sons receive tunics, sashes, and headgear, after which the text states that the priesthood belongs to them by a permanent statute.

From verse 10 the focus moves to the animals. The bull is presented first; hands are laid on its head, it is slaughtered, its blood is applied to the altar horns and poured at the base, its fat portions are burned inside, and the remainder is taken outside the camp. The first ram follows the same pattern of hand-laying and slaughter, yet its blood is splashed around the altar and the whole animal is burned. The second ram receives a longer treatment: blood is placed on the right ear, thumb, and big toe of Aaron and his sons, then mixed with anointing oil and sprinkled on the men and their clothes. Portions of this ram together with selected loaves are placed in the priests’ hands, waved, and burned; the breast is waved separately and assigned as a perpetual portion.

Verses 29-30 turn to succession: the holy garments pass to the next priest, who wears them for seven days. The eating of the ram and bread occupies verses 31-34, with the explicit rule that only the ordained may consume what has made atonement. Verse 35 summarizes the seven-day ordination and repeats the command to follow every detail given. The altar itself then receives its own seven-day purification by a daily sin offering, after which it is declared most holy.

The final movement, verses 38-46, leaves the ordination behind and establishes the daily routine that will follow: two lambs offered every morning and evening with grain and drink offerings. The repeated phrase “at the entrance of the tent of meeting” links the single consecration rite to the ongoing place where the LORD promises to meet and dwell.

What is the historical background?

The instructions for consecrating Aaron and his sons assume a setting in which a portable sanctuary, the tent of meeting, already stands at the center of Israel’s camp. In that arrangement the entrance functions as the public threshold where ordinary people encounter the sacred space, and where the washing, clothing, and anointing of the priests take place. The repeated requirement that certain actions occur “before the LORD” at this entrance reflects the ancient conviction that the deity’s presence is localized at the altar and that approach must be regulated by prescribed gestures and offerings.

Blood manipulation on the altar horns and at its base belongs to a wider pattern in which life-blood is understood to cleanse or mark what belongs to the divine realm. The same logic appears when blood from the second ram is placed on the priests’ ears, thumbs, and toes, then sprinkled on their garments. These gestures treat the human body and its clothing as surfaces that require the same purifying contact given to the altar itself. The burning of the bull’s flesh, skin, and refuse “outside the camp” further separates what has served as a sin offering from everyday life, a distinction maintained by locating the act beyond the settled area.

The seven-day repetition of the entire sequence corresponds to other periods of preparation found in Israel’s legal traditions, during which persons or objects move from ordinary to consecrated status. The garments of holiness pass from Aaron to his sons after him, establishing the priesthood as an inherited office rather than a temporary appointment. Daily offerings of two year-old lambs, one in the morning and one between the evenings, extend the same consecration forward in time so that the altar remains continually set apart and the LORD’s meeting with Israel continues at the same location where the priests were first ordained.

What does this passage teach about God?

The instructions for consecrating Aaron and his sons begin with the recognition that no one approaches the LORD without first dealing with what separates them. The bull offered as a sin offering, its blood placed on the horns of the altar and its flesh burned outside the camp, shows that sin must be removed before service can begin. The same pattern appears when the altar itself receives daily atonement for seven days, after which whatever touches it becomes consecrated. Human beings do not possess holiness by nature; it must be conferred through blood and fire.

The two rams further display the dual movement of judgment and acceptance. The first ram, burned whole as a soothing aroma and food offering, represents complete surrender. The second ram carries blood to the right ear, thumb, and big toe of each priest, marking the organs of hearing, doing, and walking as now belonging to the LORD. The same blood mixed with anointing oil is then sprinkled on the men and their garments, so that both persons and clothing share in the consecration. What remains of the offering is eaten by the priests alone in a holy place, reinforcing that those set apart for ministry receive their sustenance from what has already been accepted on the altar.

God states that he himself will consecrate the tent of meeting, the altar, and Aaron with his sons. The continual burnt offering of two lambs each day, morning and evening, sustains the place where the LORD promises to meet Israel and speak. Through these repeated acts the people are to know that the one who brought them out of Egypt now dwells in their midst as their God. The priesthood therefore exists not as an end in itself but as the means by which the covenant relationship is maintained and the glory of the LORD rests upon the sanctuary.

What are the interpretive difficulties?

One question that surfaces concerns the blood placed on the lobe of the right ear, the thumb of the right hand, and the big toe of the right foot. The command appears only with the second ram, after the sin offering and the whole burnt offering have already been completed. Nothing in the surrounding verses explains why these three points of contact receive the blood while other parts of the body do not. The procedure stands as a concrete requirement without an attached interpretation, leaving open whether the application marks the priests' capacity to hear instruction, handle offerings, and walk in the sanctuary or whether it simply identifies them as set apart.

A second issue involves the portions that move between the altar and the priests. The breast of the wave offering and the leg of the contribution are taken from the ram of setting, waved before the LORD, and then assigned to Aaron and his sons by a statute of forever. At the same time the text calls these same items contributions to the LORD. The wording does not resolve how an item can belong both to the altar and to the priests who serve there.

The closing verses introduce a further tension. After the seven-day ordination is described in detail, the LORD declares that he himself will consecrate the tent of meeting, the altar, and Aaron and his sons. The ritual instructions occupy most of the chapter, yet the final statements attribute the decisive act of consecration to the LORD's own initiative and glory. The text supplies no further comment on how the commanded actions and the divine promise relate to each other.

Finally, the daily offerings that begin in verse 38 are presented as continuing throughout the generations at the same place where the ordination takes place. The passage does not indicate whether these daily lambs simply extend the consecration rites or whether they serve a distinct purpose once the priests and altar have already been set apart.
