Leviticus 5:3-5

New Revised Standard Version Catholic Edition

³ Or when you touch human uncleanness—any uncleanness by which one can become unclean—and are unaware of it, when you come to know it, you shall be guilty. ⁴ Or when any of you utter aloud a rash oath for a bad or a good purpose, whatever people utter in an oath, and are unaware of it, when you come to know it, you shall in any of these be guilty. ⁵ When you realize your guilt in any of these, you shall confess the sin that you have committed.
