Commentary on Harmony of the Law Volume 1 Complete John Calvin
HARMONY OF THE LAW · VOLUME 1 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.
8. And thou shalt say unto them. The law is now extended to strangers, not those who were heathens, but those who, springing originally from other nations, had devoted themselves to pure religion. For, if more had been allowed to them than to the genuine children of Abraham, the corruption would, according to their wont, have soon spread more widely. God, then, would not have His sanctuary defiled by foreigners, lest their liberty might make its way amongst the whole people. From this latter portion we may gather that the word "kill" 547 which is elsewhere taken in a sense, is here confined to the sacrifices; since permission is elsewhere given to the people to eat (meat) in all their cities and villages, provided they abstain from blood. We must remember, therefore, that the question is not here as to their ordinary food, but only as to the victims, which were never to be offered except at the tabernacle.
Deuteronomy 17
Deuteronomy 17:8-11
In these verses (8, 9) the offering of a burnt-offering, or sacrifices, is only spoken of, from whence C. appears justly to conclude that the word "kill" in ver. 3, referred merely to animals killed in sacrifice.
