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.
— Leviticus 5:3-4
