Leviticus 5:3-5

New International Version

³ or if they touch human uncleanness^(A) (anything that would make them unclean)^(B) even though they are unaware of it, but then they learn of it and realize their guilt; ⁴ or if anyone thoughtlessly takes an oath^(C) to do anything, whether good or evil^(D) (in any matter one might carelessly swear about) even though they are unaware of it, but then they learn of it and realize their guilt— ⁵ when anyone becomes aware that they are guilty in any of these matters, they must confess^(E) in what way they have sinned.
