2Or if a person touches anything unclean — whether the carcass of any unclean wild animal or livestock or crawling creature —even if he is unaware of it, he is unclean and guilty.
3Or if he touches human uncleanness — anything by which one becomes unclean — even if he is unaware of it, when he realizes it, he is guilty.
4Or if someone swears thoughtlessly with his lips to do anything good or evil — in whatever matter a man may rashly pronounce an oath — even if he is unaware of it, when he realizes it, he is guilty in the matter.
5If someone incurs guilt in one of these ways, he must confess the sin he has committed,
— Leviticus 5:2-5
