The two goats formed a single sin-offering, Leviticus 16:5. To bring out the meaning of the sacrifice it was necessary that the act of a living being should be performed after death. See Leviticus 16:22 note. As this could not possibly be visibly set forth with a single victim, two were employed, as in the case of the birds in the rite for the healed leper Leviticus 14:4-6.

For the scapegoat - Rather, for Azazel. The word occurs nowhere else in the Old Testament but in this chapter, and is probably derived from a root in use in Arabic, but not in Hebrew, signifying to "remove", or "to separate".

Azazel is the pre-Mosaic name of an evil personal being placed in opposition to Yahweh. Each goat, having been presented to Yahweh before the lots were cast, stood in a sacrificial relation to Him. The casting of lots was an appeal to the decision of Yahweh (compare Joshua 7:16-17; Joshua 14:2; Proverbs 16:33; Acts 1:26, etc.); it was therefore His act to choose one of the goats for His service in the way of ordinary sacrifice, the other for His service in carrying off the sins to Azazel (see the note at Leviticus 16:22). By this exppressive outward sign the sins were sent back to the author of sin himself, "the entirely separate one," who was banished from the realm of grace.

The goat itself did not lose the sacred character with which it had been endued in being presented before Yahweh. It was, as much as the slain goat, a figure of Him who bore our griefs and carried our sorrows, on whom the Lord laid the iniquity of us all Isaiah 53:4, Isaiah 53:6, that we might become a sanctified Church to be presented unto Himself, not having spot or wrinkle or any such thing Ephesians 5:26-27.

Aaron shall cast lots upon the two goats - The Jews inform us that there were two lots made either of wood, stone, or any kind of metal. On one was written לשם Lashshem, for the Name, i. e., יהוה Jehovah, which the Jews will neither write nor pronounce: on the other was written לעזאזל Laazazel, for the Scape-Goat: then they put the two lots into a vessel which was called קלפי kalpey, the goats standing with their faces towards the west. Then the priest came, and the goats stood before him, one on the right hand and the other on the left; the kalpey was then shaken, and the priest put in both his hands and brought out a lot in each: that which was in his right hand he laid on the goat that was on his right, and that in his left hand he laid on the goat that was on his left; and according to what was written on the lots, the scape-goat and the goat for sacrifice were ascertained. See the Mishna, in Tract. Yoma. The determining this solemn business by lot, the disposal of which is with the Lord, Proverbs 16:33, shows that God alone was to select and point out the person by whom this great atonement was to be made; hence he says: Behold I lay in Zion a stone, elect (that is, chosen by himself) and precious - of infinite value.

And Aaron shall cast lots upon the two goats,.... Which should be slain, and which should be kept alive, and let go: the manner of casting lots, according to the Misnah (a), was this; the high priest went to the east of the court, to the north of the altar, the Sagan (or deputy priest) at his right hand, and Rosh Beth Ab (or the chief of the house of the fathers) on his left hand, and the two goats were there; and there was a vessel (box or urn, called Calphi), and in it were two lots of box tree: the high priest shook the Calphi (or urn) and took out the two lots; one, on which was written, "for the Lord", and the other, on which was written, "for Azazel"; if that came up on the right hand, the Sagan said to him, my lord high priest, lift up thy right hand on high; and if that on the left hand came up, Rosh Beth Ab said to him, my lord high priest, lift up thy left hand on high: he put them upon the two goats and said, a sin offering for the Lord; and they answered after him, blessed be the Lord, may the glory of his kingdom be for ever and ever: now these lots, as Ben Gersom observes, were alike, not one greater than another; and they were of the same matter, for if one had been of stone and the other of wood, they might, have been known by feeling, and so the lots would not have been legal: and the same is observed by Maimonides (b), that though they might be of any matter, of wood, or stone, or metal, yet one might not be great, and the other small, and the one of silver, and the other of gold, but both alike, for the reason before given:

one lot for the Lord, and the other lot for the scapegoat: one had written upon it, as in the above account, "for the Lord"; and the other had written upon it, "for Azazel"; directing that the goat on which the lot for the Lord fell was to be slain and offered up for a sin offering to him; and the other, on which the lot for Azazel fell, was to be kept alive and let go: now, however casual and contingent the casting of a lot may seem to men, it is certain to God, the disposal of it is of him, and according to his determination, Proverbs 16:33; and this, in the mystical sense, here denotes, that the sufferings and death of Christ were according to the determinate counsel and foreknowledge of God, and so were foretold in the Scriptures, and came to pass according to his appointment, will, and command, as was also his resurrection from the dead, John 10:18; see Acts 1:23; and likewise his conflict with Satan, John 14:30.

(a) Misn. Yoma, c. 3. sect. 9. & c. 4. sect. 1.((b) Hilchot Yom Hacippurim, c. 3. sect. 1.

And Aaron shall cast lots upon the two goats; one lot for the LORD, and the other lot for the {b} scapegoat.

(b) In Hebrew it is called Azazel, which some say is a mountain near Sinai, where this goat was sent. Rather it is called the scapegoat because it was not offered but sent into the desert, as in Le 16:11.

16:8 For the Lord - For the Lord's use by way of sacrifice. Both this and the other goat typified Christ; this in his death and passion for us; that in his resurrection for our deliverance.

scapegoat: Heb. Azazel

16:1-14 Without entering into particulars of the sacrifices on the great day of atonement, we may notice that it was to be a statute for ever, till that dispensation be at an end. As long as we are continually sinning, we continually need the atonement. The law of afflicting our souls for sin, is a statue which will continue in force till we arrive where all tears, even those of repentance, will be wiped from our eyes. The apostle observes it as a proof that the sacrifices could not take away sin, and cleanse the conscience from it, that in them there was a remembrance made of sin every year, upon the day of atonement, Heb 10:1,3. The repeating the sacrifices, showed there was in them but a feeble effort toward making atonement; this could be done only by offering up the body of Christ once for all; and that sacrifice needed not to be repeated.
