And the Lord spake unto Moses. In this, and similar passages, God appoints the priests to offer the sacrifices; for although they were common to all the people, nevertheless He would have them offered to Him by the hand of one person, and in a particular place: first, because, if they had been allowed to build altars everywhere, His pure and genuine worship would have been corrupted by this variety; and secondly, that He might direct the people to the Mediator, because this principle was ever to be held fast by believers, that no offerings could be legitimate except by His grace. The same doctrine will often occur hereafter, where the sacrifices are treated of; but, since we are here discussing the priests' office, let it be sufficient to have said once for all that it was not lawful for private persons to offer anything to God, except by the hands of the priest, to whom this duty was enjoined. But, since in this point vain glory is marvelously apt to affect men's minds, He threatens His severe vengeance against whosoever shall have attempted it. It has already been explained why God chose a single sanctuary. He now declares that, unless the victims are brought thither, this profanation will be equivalent to the murder of a man. He therefore commands that all the victims should be brought before the altar, even although those who offer them may be far away; for "the surface of the field" [1] means a distant place, lest any one should excuse himself by the inconvenience of the journey. He expressly names the peace-offerings, because that was the kind of sacrifice whereby private individuals were accustomed to testify their piety. God declares, then, that their service would be acceptable to Him, if the priest should intervene to make the oblation in right of the charge committed to him. Finally, this law is ratified unto all generations, that its abrogation may never be attempted. The reason for this is stated, which has been elsewhere more fully explained, i.e., that a single place had been ordained at which they were to assemble; and again, that a priest was appointed who might observe the ceremonies enjoined by the Law, in order that they might worship God in purity; and pollute not nor adulterate His sacrifices by strange superstitions. For we have stated that the ancient people were tied to the sanctuary, lest religion should be twisted and altered according to men's fancies, and lest any inventions should creep in whereby they might easily decline into idolatry. The commandment which He gave, then, that the priest only should offer the victims, is recommended on the score of its great usefulness; viz., because it would restrain the people from prostituting themselves to devils. Hence a profitable doctrine is gathered, that men cannot be restrained from turning away to idolatry, except by seeking from God's mouth the one simple rule of piety.

1 - "The open field," A. V.

This chapter, in its immediate bearing on the daily life of the Israelites, stands as the first of four Leviticus. 17-20 which set forth practical duties, directing the Israelites to walk, not in the way of the pagan, but according to the ordinances of Yahweh.

And the Lord spake unto Moses,.... After he had given him the law about the day of atonement, and the rites belonging to it:
saying; as follows.

All the cattle killed by the Israelites, while in the wilderness, were to be presented before the door of the tabernacle, and the flesh to be returned to the offerer, to be eaten as a peace-offering, according to the law. When they entered Canaan, this only continued in respect of sacrifices. The spiritual sacrifices we are now to offer, are not confined to any one place. We have now no temple or altar that sanctifies the gift; nor does the gospel unity rest only in one place, but in one heart, and the unity of the Spirit. Christ is our Altar, and the true Tabernacle; in him God dwells among men. It is in him that our sacrifices are acceptable to God, and in him only. To set up other mediators, or other altars, or other expiatory sacrifices, is, in effect, to set up other gods. And though God will graciously accept our family offerings, we must not therefore neglect attending at the tabernacle.

The directions are given to "Aaron and his sons, and all the children of Israel," because they were not only binding upon the nation generally, but upon the priesthood also; whereas the instructions in ch. 18-20 are addressed to "the children of Israel," or "the whole congregation" (Leviticus 18:2; Leviticus 19:2; Leviticus 20:2), just as special laws are laid down for the priests in ch. 20 and 21 with reference to the circumstances mentioned there.
