Leviticus 5:4-6

LXX2012(i) 4 That unrighteous soul, which determines with his lips to do evil or to do good according to whatever a man may determine with an oath, and it shall have escaped his notice, and he shall [afterwards] know [it], and [so] he should sin in some one of these things: 5 —then shall he declare his sin in the tings wherein he has sinned by that sin. 6 And he shall bring for his transgressions against the Lord, for his sin which he has sinned, a ewe lamb of the flock, or a kid of the goats, for a sin-offering; and the priest shall make an atonement for him for his sin which he has sinned, and his sin shall be forgiven him.
