First, Aaron was to bathe, and then to role himself in pure white, The dress is in singular contrast to the splendor of his usual official costume, in which he stood before men as representing God, and evidently signifies the purity which alone fits for entrance into the awful presence. Thus vested, he brings the whole of the animals to be sacrificed to the altar,--namely, for himself and his order, a bullock and a ram; for the people, two goats and a ram. The goats are then taken by him to the door of the tent,--and it is to be observed that they are spoken of as both constituting one sin offering (v. 5). They therefore both belong to the Lord, and are, in some important sense, one, as was recognized by the later Rabbinical prescription that they should be alike in color, size, and value. The appeal to the lot was an appeal to God to decide the parts they were respectively to sustain in a transaction which, in both parts, was really one. The consideration of the meaning of the ritual for the one which was led away may be postponed for the present. The preliminaries end with the casting of the lots, and in later times, with tying the ominous red fillet on the head of the dumb creature for which so weird a fate was in store.
