Leviticus 5:3-4

5:3 Or if he touch the uncleanness of man, whatsoever uncleanness [it be] that a man shall be defiled withal, and it be hid from him; when he knoweth [of it], then he shall be guilty. 5:4 Or if a soul swear, pronouncing with [his] lips to do evil, or to do good, whatsoever [it be] that a man shall pronounce with an oath, and it be hid from him; when he knoweth [of it], then he shall be guilty in one of these.
