Leviticus 23:19 - Matthew Poole's English Annotations on the Holy Bible

One kid: in Leviticus 4:14 the sin-offering for the sin of the people is a bullock, but here a kid, &c.; the reason of the difference may be this, because that was for some particular sin of the people, but this only in general for all their sins. If it be said, then this should have been the better sacrifice, as being for far more, and possibly greater, offences; it may be replied, that this is not the only instance wherein the greater sins are expiated by smaller sacrifices, and the smaller sins by greater sacrifices, which was to instruct us, that sins were not expiated by the sacrifices for any worth in them, but only in respect of Christ, and that, though all sins are not equal, yet they are all expiated by one and the same price, even by the blood of Christ.
