After the description of the priest’s garments, the consecration ritual for the priests is provided (Ex. 29). The opening verses set out the supplies that will be used in ceremonies described later in the chapter (Ex. 29:1-3). Next Aaron and his sons were to be washed, clothed, and anointed (Ex. 29:4-9). The washing indicates the need for cleansing before being invested with “holy garments” (Ex. 28:2). The garments are listed (calling to mind briefly the significance of each raised by the previous chapter). The anointing with oil is the symbol of the ordination.

A series of sacrifices follow the washing, investing, and anointing. The first offering was to be a sin/purification offering (Ex. 29:10-14).* This sacrifice was offered to atone for sins committed when one strayed from the commandments of God.** Next Moses was to offer a ram as a burn offering (Ex. 29:15-18). The burnt offering probably symbolized the entire consecration of the one who offered it since this sacrifice was entirely burned. The second ram, called the ram of ordination, was killed and it was used in two stages. First, its blood was applied to Aaron, his sons, and their garments (Ex 29:19-21). This sacrifice was to make the priests and their garments holy. Next this ram along with some bread was used as a wave offering. Wave offerings are often (though not always) connected with peace offerings, as is the case here (Ex. 29:28). There may be a progression here from the sin offering that provided purification from sin, to the burnt offering which symbolized entire consecration, to the ram of ordination which was used, along with the ordination, as part of a peace offering which may symbolize fellowship with God.

Exodus 29:29-30 turns the emphasis to the garments worn by the priests and it raises the matter of succession. Then follows a description of a meal from the ordination  ram (Ex. 29:31-34). This seems to indicate fellowship now made possible through atonement. This is followed by instructions for a seven day series of sin offerings and consecrations of the altar in connection with the ordination (Ex. 29:35-37).

The chapter closes by moving from the ordination to the work that the priests were ordained to do. They were to offer morning and evening sacrifices (Ex. 29:38-42). The great significance of the priesthood , and the tabernacle, and the sacrifices are found in the last verses of the chapter—Exodus 29:42-46. The tabernacle was the place where God would meet with his people. It was a holy place were this meeting could take place. Furthermore, not only would God meet with his people at the tabernacle, he would dwell among them, and he would be their God. And, in a theme that runs throughout Exodus, they would know that he is the Lord God.

*Milgrom argues for the translation “purification offering” on the grounds that (1) it is sometimes offered in cases other than to atone for sins (Lev. 8:15; 12:6; Num. 6:10) and (2) the term חַטָּאת is derived from the piel which means “to cleanse, expurgate, decontaminate.” Jacob Milgrom, “Sin-Offering or Purification-Offering?” Vetus Testamentum 21 (April 1971): 237. Averbeck accepts Milgrom’s reasoning but offers the caution, “it should not be taken to mean that the sin offering only applied to issues of physical (amoral) uncleanness. According to Leviticus 4:2, for example, it applied to ‘any of the Lord’s commandments.’” “Sacrifices and Offerings,” Dictionary of the Old Testament: Pentateuch, eds. T. Desmond Alexander and David W. Baker (Downers Grove: InterVarsity, 2003), 718.

**Roy Beacham argues that שְׁגָגָה or שׁגה, which are usually translated “unintentionally” or “sins unintentionally,” should simply be translated “in error” or “to go astray.” He argues that if the sin is unintentional there needs to be a qualifying phrase that makes that point. In arguing for this position Beacham notes it is impossible to commit the sin noted in Lev. 5:1 unintentionally. Texts outside the Pentateuch also confirm that sins designated as שְׁגָגָה or שׁגה are known sins (Psa. 119:118; Pro. 5:23; 19:27; 28:10; 1 Sam. 26:21).

Exodus 28 provides details about the garments worn by those called to serve as priests. At the beginning and ending of the chapter (Exod. 28:2, 40), God says the garments are for glory and beauty. This highlights the importance of the priestly service.

Much of the description in this chapter simply emphasizes the glory and beauty of the garments. Some of the details, however, seem to carry special significance.

Like the chapters describing the tabernacle, this chapter also emphasizes the presence of God. Several times the priest is said to enter “before Yahweh” [לִפְנֵי־יְהוָה] (Exod. 28:12, 29, 30, 35, 38). Aaron and his sons are called out of Israel to mediate between God and the nation.

The first piece of priestly clothing described in depth is the ephod (Ex. 28:6-13). Stuart notes the fabric from which the ephod was to be made matched the colors used within the Holy Place and Holy of Holies. He also notes the misuse of an ephod by Gideon. He surmises from these two facts that the ephod was a symbol of God’s presence among his people.

Exodus 28:9-12 speaks of stones with the names of the sons of Israel engraved on them. The priests bears the stones as memorials [זִכָּרֹן] before the Lord.

Thus the high priest is a mediator between God and the people. The ephod symbolizes God’s presence among the people as he moves among them wearing the gold, blue, purple, and scarlet yarns—the colors of God’s dwelling place. The stones on the shoulders of the ephod represent the people being brought into the presence of God. by the priest.

The next article of clothing, the breast-piece (Exod. 28:15-30), also emphasizes God’s presence (לִפְנֵי־יְהוָה occurs 3x in Ex. 28:29-30). The breast-piece also uses stones inscribed with the names of the sons of Israel to bring them before the Lord as a remembrance [זִכָּרֹן] (Exod. 28:29).

The breast-piece further indicates God’s presence with his people because it was used or God to render decisions [מִשְׁפָּט] from God for his people (Exod. 28:15, 30).

Exodus 28:31-35 deals with the priest’s robe. It is not clear if there is significance to the blue, the pomegranate, or the collar aside from the fact that the garments were to be made for glory and beauty. The section climaxes, however, with the need for bells on his robe as Aaron enters the holy place before the Lord so that he does not die. The words “holy place” [הַקֹּדֶשׁ] “before Yahweh” [לִפְנֵי־יְהוָה] and “not die” [וְלא יָמוּת] are key words. When someone comes before the Lord, he enters a holy place because God is holy. But for the gracious provision of God, those who enter are liable to die.

Holiness is a theme that runs throughout the chapter. God identifies the garments of the priest as “holy garments” (Exod. 28:2). The are a necessary part of his consecration to the priesthood [לְקַדְּשׁוֹ] (Exod. 28:3, 41). These are the garments necessary for Aaron to enter the Holy Place (Exod. 28:29, 35, 43).

The emphasis on holiness climaxes in Exodus 28:36-38 which deal with the plate that goes on the front of the high priest’s turban. it reads “Holiness to the Lord” [קדשׁ ליהוה]. Holiness is a key word in this section. Because of the plate Aaron could bear the iniquity of the holy things [הקדשׁים] which the sons of Israel consecrated [יקדושׁו] as holy gifts [מתנת קדשׁיהם]. Aaron does this when he comes before the Lord [לפני יהוה]. The idea seems to be that the plate declared the high priest holy and therefore worthy of bearing the iniquity of the consecrated holy gifts, thus making these offerings acceptable to God.

Verses 39-43 wrap up the instructions about clothing for the priests. Once again, as at the beginning the clothing is said to be for glory and for beauty [לכבוד ולתפארת]. The passage also notes that they should be anointed [משׁח] as part the consecration [לְקַדְּשׁוֹ] for their office.

The passage closes by describing undergarments. It may seem odd to end this list of regulations with undergarments, but if the priests’ nakedness was exposed to God’s holy things, they would die. This likely has connections back to the shame Adam and Eve had over their nakedness after they sinned and the need for clothing. It also highlights the danger in unholy man coming into the presence of God.

In the Fall mankind was thrust from God’s presence. The Tabernacle regulations and these instructions for the priest’s garments show that God’s gracious restoration of his presence to his people is no light matter. Because of his holiness and their uncleanness, the penalty for sin—death—was an ever-present threat.
