27 And if any one of the people of the land sin through inadvertence, that he do [somewhat against] any of the commandments of Jehovah [in things] which should not be done, and be guilty; 28 if his sin, which he hath sinned, come to his knowledge, then he shall bring his offering, a goat, a female without blemish, for his sin which he hath sinned. 29 And he shall lay his hand on the head of the sin-offering, and slaughter the sin-offering at the place of the burnt-offering. 30 And the priest shall take of the blood thereof with his finger, and put [it] on the horns of the altar of burnt-offering, and shall pour out all the blood thereof at the bottom of the altar. 31 And he shall take away all the fat thereof, as the fat is taken away from off the sacrifice of peace-offering; and the priest shall burn it on the altar, for a sweet odour to Jehovah; and the priest shall make atonement for him, and it shall be forgiven him. 32 And if he bring a sheep for his offering for sin, a female without blemish shall he bring it. 33 And he shall lay his hand on the head of the sin-offering, and slaughter it for a sin-offering at the place where they slaughter the burnt-offering. 34 And the priest shall take of the blood of the sin-offering with his finger, and put [it] on the horns of the altar of burnt-offering, and shall pour out all the blood thereof at the bottom of the altar. 35 And he shall take away all the fat thereof, as the fat of the lamb is taken away from the sacrifice of peace-offering; and the priest shall burn them on the altar, with Jehovah's offerings by fire; and the priest shall make atonement for him concerning his sin which he hath sinned, and it shall be forgiven him.

Commentary on Leviticus 4:27-35

(Read Leviticus 4:27-35)

Here is the law of the sin-offering for a common person. To be able to plead, when charged with sin, that we did it ignorantly, and through the surprise of temptation, will not bring us off, if we have no interest in that great plea, Christ hath died. The sins of ignorance committed by a common person, needed a sacrifice; the greatest are not above, the meanest are not below Divine justice. None, if offenders, were overlooked. Here rich and poor meet together; they are alike sinners, and welcome to Christ. From all these laws concerning the sin-offerings, we may learn to hate sin, and to watch against it; and 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. For us to err, with the Bible in our hands, is the effect of pride, sloth, and carelessness. We need to use frequent self-examination, with serious study of the Scriptures, and earnest prayer for the convincing influences of God the Holy Spirit; that we may detect our sins of ignorance, repent, and obtain forgiveness through the blood of Christ.
