John Gill's Exposition of the Whole Bible
Leviticus 6:7
And the priest shall make an atonement for him before the Lord,.... By offering the ram he brought, by which a typical, but not real atonement was made; for the blood of bulls and goats, of sheep and rams, could not take away sin; but as they were types of Christ, and led to him, the Lamb of God that takes away the sin of the world:
and it shall be forgiven him, for anything of all that he hath done, in trespassing therein; any and everyone of the above sins, with all the aggravations of them, were forgiven, upon the atonement made, though they were so enormous; and, indeed, all manner of sin is forgiven for Christ's sake, except the sin against the Holy Ghost: and L'Empereur o rightly observes, against the Socinians, who deny that sacrifices were offered for crimes very grievous, that these were of such a nature; for what more vile than unfaithfulness in a trust, than cheating and defrauding, stealing, lying, and perjury?
o In Misn. Bava Kama, c. 9. sect. 5.
