Leviticus 5:4-6

The Voice

⁴ If anyone speaks a careless vow to do something bad or something good or any careless vow for that matter—even if he was unaware of it at the time—once he realizes what he has done, he must accept the consequences. ⁵ Regarding any of these situations, when the guilty party realizes the offense, he must confess it. ⁶ He must present to Me an offering for his guilt as a remedy for the sin he has committed. This purification offering for sin must be a female lamb or goat from the flock. The priest will make atonement for the guilty person’s sin.
