15 He presented the people's offering, and took the goat of the sin offering which was for the people, and killed it, and offered it for sin, like the first.

In this first complete series of offerings made by the high priest, the sacrifices take their appointed order; first, the sin-offering to make atonement; then the burnt-offering, to signify the surrender of the body, soul and spirit to Yahweh in heaven; and lastly the peace-offering, to show forth the communion vouchsafed to those who are justified and sanctified. See Leviticus 8:14 note.
And he brought the people's offering,.... To the altar, having offered his own first:
and took the goat, which was the sin offering for the people, and slew it; where he had slain his own:
and offered it for sin, as the first: the first offering he offered for himself, which was of the same sort.
Of the sacrifices of the nation, Aaron presented the sin-offering in the same manner as the first, i.e., the one offered for himself (Leviticus 9:8.). The blood of this sin-offering, which was presented for the congregation, was not brought into the holy place according to the rule laid down in Leviticus 7:16., but only applied to the horns of the altar of burnt-offering; for the same reason as in the previous case (Leviticus 9:8.), viz., because the object was not to expiate any particular sin, or the sins of the congregation that had been committed in the course of time and remained unatoned for, but simply to place the sacrificial service of the congregation in its proper relation to the Lord. Aaron was reproved by Moses, however, for having burned the flesh (Leviticus 10:16.), but was able to justify it (see at Leviticus 10:16-20). The sin-offering (Leviticus 9:16) was also offered "according to the right" (as in Leviticus 5:10). Then followed the meat-offering (Leviticus 9:17), of which Aaron burned a handful upon the altar (according to the rule in Leviticus 2:1-2). He offered this in addition to the morning burnt-offering (Exodus 29:39), to which a meat-offering also belonged (Exodus 29:40), and with which, according to Leviticus 6:12., the special meat-offering of the priests was associated. Last of all (Leviticus 9:18-21) there followed the peace-offering, which was also carried out according to the general rule. In המכסּה, "the covering" (Leviticus 9:19), the two fat portions mentioned in Leviticus 3:3 are included. The fat portions were laid upon the breast-pieces by the sons of Aaron, and then handed by them to Aaron, the fat to be burned upon the altar, the breast to be waved along with the right leg, according to the instructions in Leviticus 7:30-36. The meat-offering of pastry, which belonged to the peace-offering according to Leviticus 7:12-13, is not specially mentioned.
