Numbers 15:25; Numbers 15:36

25 'Then the priest shall make atonement for all the congregation of the sons of Israel, and they will be forgiven; for it was an error, and they have brought their offering, an offering by fire to the LORD , and their sin offering before the LORD , for their error.

36 So all the congregation brought him outside the camp and stoned him to death with stones, just as the LORD had commanded Moses.
