The passage explains that on Yom Kippur, one lot goes to God and one lot goes to Azazel, with the scapegoat carrying away all the sins of Israel, and describes this as giving a bribe to Samael so that he will not nullify Israel's sacrifice.

AND THE OTHER LOT FOR AZAZEL. “This was a high mountain — a flinty precipitous peak, as it is said, a land which is cut off.” This is the language of Rashi. And in the Torath Kohanim [the Rabbis have said]: “For Azazel. This means the ‘hardest’ place in the mountains. I might think that it refers to an inhabited place; Scripture therefore says into the wilderness. Whence do we know that it be a precipitous peak? Scripture therefore says, unto a land which is cut off.” Accordingly the meaning of the word la’azazel is to “a hard” place, [the root of the word azazel being az — strong], with the letter za’yin doubled just like ‘izuz’ (strong) and mighty. Now Rabbi Abraham ibn Ezra wrote: “Said Rav Shmuel: ‘Although it is [only] with reference to the goat of the sin-offering that it is written [explicitly] that it was for the Eternal, the goat which was sent away [to Azazel] was also for the Eternal.’ But there is no need for this [comment]. For the goat which was sent away was not an “offering’ since it was not slaughtered. Now if you can understand the secret of the word after ‘Azazel,’ you will know its secret [that of Azazel] and the secret of its name, since it has companions in Scripture. And I will reveal to you part of the secret by hint: when you will be at thirty-three you will know it.” [Thus far are the words of Ibn Ezra]. Now of Rabbi Abraham ibn Ezra it may be said that he that is of a faithful spirit concealeth a matter, and I will not be the talebearer who revealeth his secret, since our Rabbis of blessed memory have already revealed it in many places. Thus they have said in Bereshith Rabbah: “And the ‘sa’ir’ shall carry upon him, this is a reference to Esau, as it is said, Behold, Esau my brother is a man who is ‘sa’ir’ (hairy). All ‘avonotham’ (their iniquities), [read]: ‘avonoth tam’ (the sins of him who has been called tam, ‘a man of integrity’), as it is said, and Jacob was a man ‘tam’ (‘of integrity’).” It is explained more clearly in the Chapters of the great Rabbi Eliezer: “The reason why they would give Sammael [i.e., Satan] a conciliatory gift on the Day of Atonement, was so that he should not annul [the effect of] their offerings, as it is said, one lot for the Eternal, and the other lot for Azazel, the lot of the Holy One, blessed by He, to be a burnt-offering, and the lot of Azazel to be ‘the goat of sin,’ bearing upon it all the iniquities of Israel, as it is said, And the goat shall bear upon him all their iniquities. When Sammael saw that he could find no sin on the Day of Atonement amongst them [the children of Israel], he said to the Holy One, blessed by He: ‘Master of all worlds! You have one people on earth who are comparable to the ministering angels in the heavens. Just as the ministering angels are barefooted, so are the Israelites barefooted [i.e., do not wear leather shoes] on the Day of Atonement. Just as the ministering angels do not eat or drink, so is there no eating or drinking in Israel on the Day of Atonement. Just as the ministering angels have no joints [in their feet, and therefore cannot sit or lie down], so do the Israelites stand on their feet on the Day of Atonement. Just as there is peace in the midst of the ministering angels, so do the Israelites bring peace among themselves on the Day of Atonement. Just as the ministering angels are free from all sin, so are the Israelites free from all sin on the Day of Atonement.’ And the Holy One, blessed be He, hears the testimony concerning Israel from their prosecutor, and He atones for the altar and for the Sanctuary, and for the priests and for all the people of the assembly, as it is said, And he shall make atonement for the most holy place etc.” Thus far is the language of this Agadah (tradition) in which the Rabbis have informed us of his name [i.e., Sammael] and the nature of his deeds. Now this is the secret of the matter. They used to worship “other gods,” namely, the angels, bringing offerings of a sweet savor to them, similarly to that which it says, and thou didst set Mine oil and My incense before them. My bread also which I gave thee, fine flour, and oil, and honey, wherewith I fed thee, thou didst even set it before them for a sweet savor, and thus it was; saith the Eternal G-d. You have to contemplate the Scriptural text as it is written and [also] as [it is read according to the] Masoretic tradition. Now the Torah has absolutely forbidden to accept them as deities, or to worship them in any manner. However, the Holy One, blessed be He, commanded us that on the Day of Atonement we should let loose a goat in the wilderness, to that “prince” [power] which rules over wastelands, and this [goat] is fitting for it because he is its master, and destruction and waste emanate from that power, which in turn is the cause of the stars of the sword, wars, quarrels, wounds, plagues, division and destruction. In short, it is the spirit of the sphere of Mars, and its portion among the nations is Esau [Rome], the people that inherited the sword and the wars, and among animals [its portion consists of] the se’irim (demons) and the goats. Also in its portion are the devils called “destroyers” in the language of our Rabbis, and in the language of Scripture: se’irim (satyrs, demons), for thus he [i.e., Esau] and his nation were called sa’ir. Now the intention in our sending away the goat to the desert was not that it should be an offering from us to it — Heaven forbid! Rather, our intention should be to fulfill the wish of our Creator, Who commanded us to do so. This may be compared to the case of someone who makes a feast for his master, and the master commands the person making the feast, “Give one portion to that servant of mine,” in which case the host gives nothing [of his own] to that servant, and it is not to show him honor that he acts in that way to him, but everything is given to the master and it is the master that gives a gift to his servant; the host only observes his command and does in honor of the master whatever he commanded him to do. The master, however, out of his own compassion for the host, wanted all his servants to derive some enjoyment from it [the feast], in order that they may all speak of his [the host’s] praise and not of his shortcomings. This then is the reason [for having someone] who casts the lots [on the two goats]. If the priest were to dedicate them merely, by word of mouth [without casting the lots], saying, “one for the Eternal” and “one for Azazel,” that would be like worshipping [Azazel] or taking a vow in its name. Rather, the priest set the two goats before the Eternal at the door of the Tent of Meeting, for both of them were a gift to G-d, and he gave to His servant that portion which came to him from G-d. It is he [i.e., the priest] who cast the lots on them, but it is His hand that apportioned them, something like that which it says, The lot is cast into the lap; but the whole disposing of it is of the Eternal. Even after the casting of the lots, the priest placed the two goats before the Eternal, thus proclaiming that both are His and that by sending one away [to the desert] we intend merely to fulfill G-d’s wish, just as it said, And the goat, on which the lot fell for Azazel, shall be set alive ‘before the Eternal,’ to make atonement over him, to send him away etc. That is the reason why we do not ourselves do any act of slaughtering [of that goat, as this would imply that it is a proper offering which requires slaughtering]. And Onkelos rendered the expression (one lot for the Eternal, and one lot for Azazel) as: “one lot for ‘the Name of’ the Eternal and one lot for Azazel;” [thus he was careful not to translate “and one lot for the name of Azazel”], because the one was “for the Name of the Eternal” and not for him [Azazel], and the second was “for Azazel” but not “for the name of Azazel.” It is for this reason that our Rabbis have interpreted: “And My statutes shall ye keep. These are matters against which the evil inclination raises accusations, and the idolaters likewise bring charges, such as the [prohibition against] wearing clothes made of a mixture of wool and linen, [the law of] the Red Heifer, and of the goat that is sent away [to Azazel].” Now these idolaters have not accused us [according to our Rabbis] in connection with the offerings, for these are the fire-offerings unto the Eternal. But they accuse us in connection with the goat that is sent away [to Azazel], because they think that we act as they do. Similarly they accuse us in connection with the Red Heifer, because it is slaughtered without the camp, but [in truth] the purport thereof is analogous to that of the goat sent away [to Azazel], which is to remove the spirit of impurity, as it is said of the future, And also I will cause the [false] prophets and the unclean spirit to pass out of the Land. On this basis you will understand the reason why the person who sent forth the goat to Azazel must wash his garments [as they were rendered impure], and likewise he who burns the Red Heifer, and what our Rabbis have mentioned concerning the requirement of washing the garments [of those priests who are in charge] of the burning of the bulls and he-goats which were to be wholly burnt [outside the camp, i.e., outside the city of Jerusalem]. Thus Rabbi Abraham ibn Ezra intimated to you that you will know the secret of [sending away the goat to Azazel] when you reach the verse, And they shall no more sacrifice their sacrifices unto the satyrs. The word [Azazel] is a compound one [made of two words]. There are many such cases. Thus the matter is explained, unless you pursue a further investigation from this subject to that of the Separate Intelligences and how the spirits [are affected by] the offerings — [the influence upon the spirits] being known through the study of necromancy, while that of the [Separate] Intelligences is known by means of certain allusions of the Torah to those who understand their secrets. I cannot explain more, for I would have to close the mouths of those who claim to be wise in the study of nature, following after that Greek [philosopher Aristotle] who denied everything except that which could be perceived by him [through the physical senses], and he, and his wicked disciples, were so proud as to suspect that whatever he could not conceive of through his reasoning is not true!
