Leviticus 5:4 WBT

²  Or if a soul shall touch any unclean thing, whether a carcass of an unclean beast, or a carcass of unclean cattle, or the carcass of unclean creeping animals, and it shall be hidden from him; he also shall be unclean, and guilty.

³  Or if he shall touch the uncleanness of man, whatever uncleanness [it may be] that a man shall be defiled with, and it be hid from him; when he knoweth [of it], then he shall be guilty.

⁴  Or if a soul shall swear, pronouncing with [his] lips to do evil, or to do good, whatever [it may 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.

⁵  And it shall be, when he shall be guilty in one of these [things], that he shall confess that he hath sinned in that [thing]:

⁶  And he shall bring his trespass-offering to the LORD for his sin which he hath sinned, a female from the flock, a lamb or a kid of the goats, for a sin-offering; and the priest shall make an atonement for him concerning his sin.
