Numbers 15:25-26
15:25 And the priest is to make atonement for the whole community of the Israelites, and they will be forgiven, because it was unintentional and they have brought their offering, an offering made by fire to the Lord, and their purification offering before the Lord, for their unintentional offense.
15:26 And the whole community of the Israelites and the resident foreigner who lives among them will be forgiven, since all the people were involved in the unintentional offense.
