Leviticus 5:6

3 Or if he touch the uncleanness of man, whatsoever his uncleanness be wherewith he is unclean, and it be hid from him; when he knoweth of it, then he shall be guilty.

4 Or if any one swear rashly with his lips to do evil, or to do good, whatsoever it be that a man shall utter rashly with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these [things].

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

6 and he shall bring his trespass-offering unto Jehovah for his sin which he hath sinned, a female from the flock, a lamb or a goat, for a sin-offering; and the priest shall make atonement for him as concerning his sin.

7 And if his means suffice not for a lamb, then he shall bring his trespass-offering for that wherein he hath sinned, two turtle-doves, or two young pigeons, unto Jehovah; one for a sin-offering, and the other for a burnt-offering.

8 And he shall bring them unto the priest, who shall offer that which is for the sin-offering first, and wring off its head from its neck, but shall not divide it asunder:

9 and he shall sprinkle of the blood of the sin-offering upon the side of the altar; and the rest of the blood shall be drained out at the base of the altar: it is a sin-offering.
