Unto Eleazar the priest. Possibly in order that Aaron himself might not be associated with dearly, even in this indirect way (see Numbers 19:6). In after times, however, it was usually the high priest who officiated on this occasion, and therefore it is quite as likely that Eleazar was designated because he was already beginning to take the place of his father in his especial duties. Without the camp. The bodies of those animals which were offered for the sin of the congregation were always burnt outside the camp, the law thus testifying that sin and death had no proper place within the city of God. In this case, however, the whole sacrifice was performed outside the camp, and was only brought into relation with the national sanctuary by the sprinkling of the blood in that direction. Various symbolic reasons have been assigned to this fact, but none are satisfactory except the following:—
1. It served to intensify the conviction, which the whole of this ordinance was intended to bring home to the minds of men, that death was an awful thing, and that everything connected with it was wholly foreign to the presence and habitation of the living God.
2. It served to mark with more emphasis the contrast between this one offering, which was perhaps almost the only one they had in the wilderness, and those which ought to have been offered continually according to the Levitical ordinances. The red heifer stood quite outside the number of ordinary victims as demanded by the law, and therefore it was not slain at any hallowed altar, nor, necessarily, by any hallowed hand.
3. It served to prefigure in a wonderful and indeed startling way the sacrifice of Christ outside the gate. In later days the heifer was conducted upon a double tier of arches over the ravine of Kedron to the opposite slope of Olivet. That he may bring her forth … and one shall slay her. The nominative to both these verbs is alike unexpressed. Septuagint, καὶ ἐξάξουσιν … καὶ σφάξουσιν. In the practice of later ages the high priest led her out, and another priest killed her in his presence, but it was not so commanded.
