I. Here is the law of the sin-offering for a common person, which differs from that for a ruler only in this, that a private person might bring either a kid or a lamb, a ruler only a kid; and that for a ruler must be a male, for the other a female: in all the circumstances of the management of the offering they agreed. Observe, 1. The case supposed: If any one of the common people sin through ignorance, Lev. 4:27. The prophet supposes that they were not so likely as the great men to know the way of the Lord, and the judgment of their God (Jer. 5:4), and yet, if they sin through ignorance, they must bring a sin-offering. Note, Even sins of ignorance need to be atoned for by sacrifice. To be able to plead, when we are charged with sin, that we did it ignorantly, and through the surprise of temptation, will not bring us off if we be not interested in that great plea, Christ hath died, and entitled to the benefit of that. We have all need to pray with David (and he was a ruler) to be cleansed from secret faults, the errors which we ourselves do not understand or are not aware of, Ps. 19:12. 2. That the sins of ignorance committed by a single person, a common obscure person, did require a sacrifice; for, as the greatest are not above the censure, so the meanest are not below the cognizance of the divine justice. None of the common people, if offenders, were overlooked in a crowd. 3. That a sin-offering was not only admitted, but accepted, even from one of the common people, and an atonement made by it, Lev. 4:31, 35. Here rich and poor, prince and peasant, meet together; they are both alike welcome to Christ, and to an interest in his sacrifice, upon the same terms. See Job 34:19.
II. From all these laws concerning the sin-offerings we may learn, 1. To hate sin, and to watch against it. That is certainly a very bad thing to make atonement for which so many innocent and useful creatures must be slain and mangled thus. 2. To value Christ, the great and true sin-offering, whose blood cleanses from all sin, which it was not possible that the blood of bulls and of goats should take away. Now, if any man sin, Christ is the propitiation (1 John 2:1, 2), not for Jews only, but for Gentiles. And perhaps there was some allusion to this law concerning sacrifices for sins of ignorance in that prayer of Christ’s, just when he was offering up himself a sacrifice, Father, forgive them, for they know not what they do.
