25 And the priest shall make atonement for all the congregation of the people of Israel, and they shall be forgiven, because it was a mistake, and they have brought their offering, a food offering to the Lord, and their sin offering before the Lord for their mistake.
Matthew Henry's Commentary on Numbers 15:25
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.
