22 And if ye sin inadvertently, and do not all these commandments, which Jehovah hath spoken unto Moses, 23 all that Jehovah hath commanded you through Moses, from the day that Jehovah gave commandment, and henceforward throughout your generations; 24 then it shall be, if ought be committed by inadvertence [hid] from the eyes of the assembly, that the whole assembly shall offer one young bullock for a burnt-offering, for a sweet odour to Jehovah, and its oblation and its drink-offering according to the ordinance, and one buck of the goats for a sin-offering. 25 And the priest shall make atonement for the whole assembly of the children of Israel, and it shall be forgiven them; for it was a sin of inadvertence, and they have brought before Jehovah their offering, as an offering by fire to Jehovah, and their sin-offering for their [sin of] inadvertence; 26 and it shall be forgiven the whole assembly of the children of Israel, and the stranger that sojourneth among them; for with all the people there was [a sin of] inadvertence. 27 And if one soul sin through inadvertence, then he shall present a yearling she-goat for a sin-offering. 28 And the priest shall make atonement for the soul that hath done inadvertently, when he sinneth by inadvertence before Jehovah, to make atonement for him; and it shall be forgiven him. 29 For him that is born in the land among the children of Israel, and for the stranger that sojourneth among them—there shall be one law for you, for him who doeth anything through inadvertence.

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.
