27 "If any one of the common people sins unwittingly in doing any one of the things which the Lord has commanded not to be done, and is guilty, 28 when the sin which he has committed is made known to him he shall bring for his offering a goat, a female without blemish, for his sin which he has committed. 29 And he shall lay his hand on the head of the sin offering, and kill the sin offering in the place of burnt offering. 30 And the priest shall take some of its blood with his finger and put it on the horns of the altar of burnt offering, and pour out the rest of its blood at the base of the altar. 31 And all its fat he shall remove, as the fat is removed from the peace offerings, and the priest shall burn it upon the altar for a pleasing odor to the Lord; and the priest shall make atonement for him, and he shall be forgiven. 32 "If he brings a lamb as his offering for a sin offering, he shall bring a female without blemish, 33 and lay his hand upon the head of the sin offering, and kill it for a sin offering in the place where they kill the burnt offering. 34 Then the priest shall take some of the blood of the sin offering with his finger and put it on the horns of the altar of burnt offering, and pour out the rest of its blood at the base of the altar. 35 And all its fat he shall remove as the fat of the lamb is removed from the sacrifice of peace offerings, and the priest shall burn it on the altar, upon the offerings by fire to the Lord; and the priest shall make atonement for him for the sin which he has committed, and he shall be forgiven.

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.
