Adam Clarke Bible Commentary
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, Pro 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.
John Gill Bible Commentary
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, Pro 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, Joh 10:18; see Act 1:23; and likewise his conflict with Satan, Joh 14:30.

Tyndale Open Study Notes
16:8 The Hebrew term ‘aza’zel (Azazel) is found only in 16:8, 10, 26. This word has generally been interpreted in four different ways: (1) as a word meaning “the goat of going away”; (2) as a demon that lived in the wilderness; (3) as a strengthened form of the Hebrew word for “go, leave,” meaning “utter loss”; and (4) as a rocky cliff over which the goat was pushed. Since this goat represented the removal of the sins of Israel from the camp (16:22), the first interpretation is probably the simplest solution.
