Numbers 15:24-25

24and it is done unintentionally out of sight of the community, then the entire community is to offer one young bull from the herd for a burnt offering as a pleasing aroma to Adonai, along with its appropriate grain offering and drink offering, and one male goat as a sin offering.

25So the kohen will make atonement for the entire community of Bnei-Yisrael, and they will be forgiven, for it was unintentional and they brought a fire offering and their sin offering to Adonai for their error.
