Leviticus 5:1-7

“ ‘If a person is ordered to tell in court what he has seen or what he knows and he does not tell the court, he is guilty of sin. “ ‘Or someone might touch something unclean, such as the dead body of an unclean wild animal or an unclean farm animal or an unclean crawling animal. Even if he does not know that he touched it, he will still be unclean and guilty of sin. “ ‘Someone might touch human uncleanness—anything that makes someone unclean—and not know it. But when he learns about it, he will be guilty. “ ‘Or someone might make a promise before the LORD without thinking. It might be a promise to do something bad or something good; it might be about anything. Even if he forgets about it, when he remembers, he will be guilty. “ ‘When anyone is guilty of any of these things, he must tell how he sinned. He must bring an offering to the LORD as a penalty for sin; it must be a female lamb or goat from the flock. The priest will perform the acts to remove that person’s sin so he will belong to the LORD. “ ‘But if the person cannot afford a lamb, he must bring two doves or two young pigeons to the LORD as the penalty for his sin. One bird must be for a sin offering, and the other must be for a whole burnt offering.
