Leviticus 5:17-19

“If anyone sins by breaking any of the commandments of GOD which must not be broken, but without being aware of it at the time, the moment he does realize his guilt he is held responsible. He is to bring to the priest a ram without any defect, assessed at the value of the Compensation-Offering. “Thus the priest will make atonement for him for his error that he was unaware of and he’s forgiven. It is a Compensation-Offering; he was surely guilty before God.”
