Leviticus 4:2-3

2Speak unto the children of Israel, saying, If a soul shall sin through inadvertence against any of the commandments of Jehovah [in things] that ought not to be done, and do any of them;

3if the priest that is anointed sin according to the trespass of the people; then for his sin which he hath sinned shall he present a young bullock without blemish to Jehovah for a sin-offering.
