27 'Also if one person sins unintentionally , then he shall offer a one year old female goat for a sin offering . 28 ' The priest shall make atonement before the Lord for the person who goes astray when he sins unintentionally , making atonement for him that he may be forgiven . 29 'You shall have one law for him who does anything unintentionally , for him who is native among the sons of Israel and for the alien who sojourns among them.

30 'But the person who does anything defiantly e , whether he is native or an alien , that one is blaspheming the Lord ; and that person shall be cut off from among his people . 31 'Because he has despised the word of the Lord and has broken His commandment , that person shall be completely cut off ; his guilt will be on him.' "

Commentary on Numbers 15:22-29

(Read Numbers 15:22-29)

Though ignorance will in a degree excuse, it will not justify those who might have known their Lord's will, yet did it not. David prayed to be cleansed from his secret faults, those sins which he himself was not aware of. Sins committed ignorantly, shall be forgiven through Christ the great Sacrifice, who, when he offered up himself once for all upon the cross, seemed to explain one part of the intention of his offering, in that prayer, Father, forgive them, for they know not what they do. It looked favourably upon the Gentiles, that this law of atoning for sins of ignorance, is expressly made to extend to those who were strangers to Israel.

Commentary on Numbers 15:30-36

(Read Numbers 15:30-36)

Those are to be reckoned presumptuous sinners, who sin designedly against God's will and glory. Sins thus committed are exceedingly sinful. He that thus breaks the commandment reproaches the Lord. He also despises the word of the Lord. Presumptuous sinners despise it, thinking themselves too great, too good, and too wise, to be ruled by it. A particular instance of presumption in the sin of sabbath-breaking is related. The offence was gathering sticks on the sabbath day, to make a fire, whereas the people were to bake and seethe what they had occasion for, the day before, Exodus 16:23. This was done as an affront both to the law and to the Lawgiver. God is jealous for the honour of his sabbaths, and will not hold him guiltless who profanes them, whatever men may do. God intended this punishment for a warning to all, to make conscience of keeping holy the sabbath. And we may be assured that no command was ever given for the punishment of sin, which, at the judgment day, shall not prove to have come from perfect love and justice. The right of God to a day of devotion to himself, will be disputed and denied only by such as listen to the pride and unbelief of their hearts, rather than to the teaching of the Spirit of truth and life. Wherein consists the difference between him who was detected gathering sticks in the wilderness on the day of God, and the man who turns his back upon the blessings of sabbath appointments, and the promises of sabbath mercies, to use his time, his cares, and his soul, in heaping up riches; and waste his hours, his property, and his strength in sinful pleasure? Wealth may come by the unhallowed effort, but it will not come alone; it will have its awful reward. Sinful pursuits lead to ruin.
