Numbers 15:24-26

²⁴then 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.

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.
