27 And if any one of the common people does wrong in error, doing any of the things which the Lord has given orders are not to be done, causing sin to come on him; 28 When the sin which he has done is made clear to him, then he is to give for his offering a goat, a female without any mark, for the sin which he has done. 29 And he is to put his hand on the head of the sin-offering and put it to death in the place where they put to death the burned offering. 30 And the priest is to take some of the blood with his finger, and put it on the horns of the altar of burned offering, and all the rest of its blood is to be drained out at the base of the altar. 31 And let all its fat be taken away, as the fat is taken away from the peace-offerings, and let it be burned on the altar by the priest for a sweet smell to the Lord; and the priest will take away his sin and he will have forgiveness. 32 And if he gives a lamb as his sin-offering, let it be a female without any mark; 33 And he is to put his hand on the head of the offering and put it to death for a sin-offering in the place where they put to death the burned offering. 34 And the priest is to take some of the blood of the offering with his finger and put it on the horns of the altar of burned offering, and all the rest of the blood is to be drained out at the base of the altar; 35 And let him take away all its fat, as the fat is taken away from the lamb of the peace-offerings; and let it be burned by the priest on the altar among the offerings made by fire to the Lord: and the priest will take away his sin and he will have forgiveness.

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.
