Leviticus 5:18-19

New American Standard Bible

¹⁸ He is then to bring to the priest ^(A)a ram without defect from the flock, according to your assessment, as a guilt offering. So the priest shall make atonement for him concerning his sin which he committed ^(B)unintentionally and did not know it, and it will be forgiven him. ¹⁹ It is a guilt offering; he was certainly guilty before the Lord.”
