Numbers 15:25-26

25And 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;

26and 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.
