Leviticus 5:17-19

Amplified Bible

¹⁷ “Now if anyone sins and does any of the things which the Lord has forbidden, though he was not aware of it, still he is guilty and shall bear his punishment.^{(A) 18} He is then to bring to the priest a ram without blemish from the flock, according to your valuation, for a guilt offering. In this way the priest shall make atonement for him regarding the error which he committed unintentionally and did not know it, and he shall be forgiven. ¹⁹ It is a guilt offering; he was certainly guilty before the Lord.”
