Leviticus 5:4-6

Webster(i) 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.
