Leviticus 5:4-6

VIN(i) 4 »When you pledge a vow in haste about what you will or will not do, as some people do, and then ignore it; although you know what you said, you will be guilty. 5 When he becomes guilty in any of these, he shall confess what he has sinned regarding it, 6 and he shall bring his guilt offering to the LORD for his sin that he has committed: a female from the flock, a ewe-lamb or a she-goat, as a sin offering, and the priest shall make atonement for him for his sin.
