Numbers 30:11-12

MLV(i) 11 and her husband heard it and remained silent at her and did not disallow her, then all her vows will stand and every bond with which she bound her soul will stand. 12 But if her husband made them null and void in the day that he heard them, then whatever proceeded out of her lips concerning her vows, or concerning the bond of her soul, will not stand. Her husband has made them void and Jehovah will forgive her.
