27 And if any one  of the common people sin through ignorance, while he doeth somewhat against any of the commandments of the Lord concerning things which ought not to be done, and be guilty;
27 " 'If any member of the community sins unintentionally and does what is forbidden in any of the Lord's commands, when they realize their guilt
27 "If anyone of the common people sins unintentionally in doing any one of the things that by the Lord's commandments ought not to be done, and realizes his guilt,
27 "When an ordinary member of the congregation sins unintentionally, straying from one of the commandments of God which must not be broken, he is guilty.
27 'If anyone of the common people sins unintentionally by doing something against any of the commandments of the Lord in anything which ought not to be done, and is guilty,
27 "If any of the common people sin by violating one of the Lord 's commands, but they don't realize it, they are still guilty.
Matthew Henry's Commentary on Leviticus 4:27
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.
