22 But if you unintentionally fail to observe all these commandments that the Lord has spoken to Moses- 23 everything that the Lord has commanded you by Moses, from the day the Lord gave commandment and thereafter, throughout your generations- 24 then if it was done unintentionally without the knowledge of the congregation, the whole congregation shall offer one young bull for a burnt offering, a pleasing odor to the Lord, together with its grain offering and its drink offering, according to the ordinance, and one male goat for a sin offering. 25 The priest shall make atonement for all the congregation of the Israelites, and they shall be forgiven; it was unintentional, and they have brought their offering, an offering by fire to the Lord, and their sin offering before the Lord, for their error. 26 All the congregation of the Israelites shall be forgiven, as well as the aliens residing among them, because the whole people was involved in the error. 27 An individual who sins unintentionally shall present a female goat a year old for a sin offering. 28 And the priest shall make atonement before the Lord for the one who commits an error, when it is unintentional, to make atonement for the person, who then shall be forgiven. 29 For both the native among the Israelites and the alien residing among them-you shall have the same law for anyone who acts in error.

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.
