19:3 And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and {b} [one] shall slay her before his face:
(b) Another priest.
19:3 Eleazar - Who was the second priest, and in some cases, the deputy of the high - priest. To him, not to Aaron, because this service made him unclean for a season, and consequently unfit for holy ministrations, whereas the high - priest was, as far as possibly he could, to be preserved from all sorts of defilement, fit for his high and holy work. Without the camp - Partly because it was reputed an unclean and accursed thing, being laden with the sins of all the people; and partly to signify that Christ should suffer without the camp, in the place where malefactors suffered.
19:1-10 The heifer was to be wholly burned. This typified the painful sufferings of our Lord Jesus, both in soul and body, as a sacrifice made by fire, to satisfy God's justice for man's sin. These ashes are said to be laid up as a purification for sin, because, though they were only to purify from ceremonial uncleanness, yet they were a type of that purification for sin which our Lord Jesus made by his death. The blood of Christ is laid up for us in the word and sacraments, as a fountain of merit, to which by faith we may have constant recourse, for cleansing our consciences.
