Lev 16:2-3 | KD | STEP | The chronological link connecting the following law with the death of the sons of Aaron ( ) was intended, not only to point out the historical event which led to the appointment of the day of atonement, but also to show the importance and holiness attached to an entrance into the inmost sanctuary of God. The death of Aaron’s sons, as a punishment for wilfully “drawing near before Jehovah,” was to be a solemn warning to Aaron himself, “not to come at all times into the holy place within the vail, before the mercy-seat upon the ark,” i.e., into the most holy place (see Exo 25:10.), but only at the time to be appointed by Jehovah, and for the purposes instituted by Him, i.e., according to Lev 16:29., only once a year, on the day of atonement, and only in the manner prescribed in Lev 16:3., that he might not die. - “For I will appear in the cloud above the capporeth.” The cloud in which Jehovah appeared above the capporeth, between the cherubim ( ), was not the cloud of the incense, with which Aaron was to cover the capporeth on entering ( ), as Vitringa, Bähr, and others follow the Sadducees in supposing, but the cloud of the divine glory, in which Jehovah manifested His essential presence in the most holy place above the ark of the covenant. Because Jehovah appeared in this cloud, not only could no unclean and sinful man go before the capporeth, i.e., approach the holiness of the all-holy God; but even the anointed and sanctified high priest, if he went before it at his own pleasure, or without the expiatory blood of sacrifice, would expose himself to certain death. The reason for this prohibition is to be found in the fact, that the holiness communicated to the priest did not cancel the sin of his nature, but only covered it over for the performance of his official duties, and so long as the law, which produced only the knowledge of sin and not its forgiveness and removal, was not abolished by the complete atonement, the holy God was and remained to mortal and sinful man a consuming fire, before which no one could stand.

‏ Leviticus 16:2-3

The chronological link connecting the following law with the death of the sons of Aaron (Lev 10:1-5) was intended, not only to point out the historical event which led to the appointment of the day of atonement, but also to show the importance and holiness attached to an entrance into the inmost sanctuary of God. The death of Aaron’s sons, as a punishment for wilfully “drawing near before Jehovah,” was to be a solemn warning to Aaron himself, “not to come at all times into the holy place within the vail, before the mercy-seat upon the ark,” i.e., into the most holy place (see Exo 25:10.), but only at the time to be appointed by Jehovah, and for the purposes instituted by Him, i.e., according to Lev 16:29., only once a year, on the day of atonement, and only in the manner prescribed in Lev 16:3., that he might not die. - “For I will appear in the cloud above the capporeth.” The cloud in which Jehovah appeared above the capporeth, between the cherubim (Exo 25:22), was not the cloud of the incense, with which Aaron was to cover the capporeth on entering (Lev 16:13), as Vitringa, Bähr, and others follow the Sadducees in supposing, but the cloud of the divine glory, in which Jehovah manifested His essential presence in the most holy place above the ark of the covenant. Because Jehovah appeared in this cloud, not only could no unclean and sinful man go before the capporeth, i.e., approach the holiness of the all-holy God; but even the anointed and sanctified high priest, if he went before it at his own pleasure, or without the expiatory blood of sacrifice, would expose himself to certain death. The reason for this prohibition is to be found in the fact, that the holiness communicated to the priest did not cancel the sin of his nature, but only covered it over for the performance of his official duties, and so long as the law, which produced only the knowledge of sin and not its forgiveness and removal, was not abolished by the complete atonement, the holy God was and remained to mortal and sinful man a consuming fire, before which no one could stand. Lev 16:3-5

Only בּזאת, “with this,” i.e., with the sacrifices, dress, purifications, and means of expiation mentioned afterwards, could he go into “the holy place,” i.e., according to the more precise description in Lev 16:2, into the inmost division of the tabernacle, which is called Kodesh hakkadashim, “the holy of holies,” in Exo 26:33. He was to bring an ox (bullock) for a sin-offering and a ram for a burnt-offering, as a sacrifice for himself and his house (i.e., the priesthood, Lev 16:6), and two he-goats for a sin-offering and a ram for a burnt-offering, as a sacrifice for the congregation. For this purpose he was to put on, not the state-costume of the high priest, but a body-coat, drawers, girdle, and head-dress of white cloth (bad: see Exo 28:42), having first bathed his body, and not merely his hands and feet, as he did for the ordinary service, to appear before Jehovah as entirely cleansed from the defilement of sin (see at Lev 8:6) and arrayed in clothes of holiness. The dress of white cloth was not the plain official dress of the ordinary priests, for the girdle of that dress was coloured (see at Exo 28:39-40); and in that case the high priest would not have appeared in the perfect purity of his divinely appointed office as chief of the priesthood, but simply as the priest appointed for this day (v. Hoffmann). Nor did he officiate (as many of the Rabbins, and also C. a Lapide, Grotius, Rosenmüller, and Knobel suppose) as a penitent praying humbly for the forgiveness of sin. For where in all the world have clear white clothes been worn either in mourning or as a penitential garment? The emphatic expression, “these are holy garments,” is a sufficient proof that the pure white colour of all the clothes, even of the girdle, was intended as a representation of holiness. Although in Exo 28:2, Exo 28:4, etc., the official dress not only of Aaron, but of his sons also, that is to say, the priestly costume generally, is described as “holy garments,” yet in the present chapter the word kodesh, “holy,” is frequently used in an emphatic sense (for example, in Lev 16:2, Lev 16:3, Lev 16:16, of the most holy place of the dwelling), and by this predicate the dress is characterized as most holy. Moreover, it was in baddim (“linen”) that the angel of Jehovah was clothed (Eze 9:2-3, Eze 9:11; Eze 10:2, Eze 10:6-7, and Dan 10:5; Dan 12:6-7), whose whole appearance, as described in Dan 10:6, resembled the appearance of the glory of Jehovah, which Ezekiel saw in the vision of the four cherubim (ch. 1), and was almost exactly like the glory of Jesus Christ, which John saw in the Revelation (Rev 1:13-15). The white material, therefore, of the dress which Aaron wore, when performing the highest act of expiation under the Old Testament, was a symbolical shadowing forth of the holiness and glory of the one perfect Mediator between God and man, who, being the radiation of the glory of God and the image of His nature, effected by Himself the perfect cleansing away of our sin, and who, as the true High Priest, being holy, innocent, unspotted, and separate from sinners, entered once by His own blood into the holy place not made with hands, namely, into heaven itself, to appear before the face of God for us, and obtain everlasting redemption (Heb 1:3; Heb 7:26; Heb 9:12, Heb 9:24).
