Numbers 15:24-25

24If it was unintentional and no one else knows about it, the whole community must sacrifice a young bull as a burnt offering, a soothing aroma to the Lord, along with the proper grain and wine offerings, and a male goat as an offering for sin.

25The priest will make peace with the Lord for the whole community of Israel. Then they will be forgiven because the wrongdoing was unintentional and they brought these two offerings to the Lord for their sin: an offering by fire and an offering for sin.
