Leviticus 5:2-6

²Or if a man shall have touched anything unclean, whether the carcase of an unclean beast, or the carcase of unclean cattle, or the carcase of an unclean reptile, and it be hidden from him, he shall be defiled and guilty.

³Or if he shall touch the uncleanness of a man, any uncleanness which defileth him, and it be hidden from him; but (afterwards) becometh aware of it and is guilty;

⁴Or if a man swear, declaring with his lips, for evil or for good, according to whatever the man shall declare by oath, and (the truth) be hidden from him, and he (afterwards) have knowledge thereof, he is guilty of one of these.

⁵And it shall be that when (he knoweth that) he is guilty in one of these (things) he shall confess that he hath sinned thereby;

⁶And shall bring his sin offering before the Lord for the sin that he hath sinned; a she-lamb from the flock, or a kid of the goats, for a sin offering; and the priest shall atone for him and for his sin.
