Numbers 15:26 WEB

²⁴  then it shall be, if it be done unwittingly, without the knowledge of the congregation, that all the congregation shall offer one young bull for a burnt offering, for a sweet savor to Yahweh, with the meal-offering of it, and the drink-offering of it, according to the ordinance, and one male goat for a sin-offering.

²⁵  The priest shall make atonement for all the congregation of the children of Israel, and they shall be forgiven; for it was an error, and they have brought their offering, an offering made by fire to Yahweh, and their sin-offering before Yahweh, for their error:

²⁶  and all the congregation of the children of Israel shall be forgiven, and the stranger who lives as a foreigner among them; for in respect of all the people it was done unwittingly.

²⁷  If one person sin unwittingly, then he shall offer a female goat a year old for a sin-offering.

²⁸  The priest shall make atonement for the soul who errs, when he sins unwittingly, before Yahweh, to make atonement for him; and he shall be forgiven.
