Numbers 30:2-5

MKJV(i) 2 If a man vows a vow to Jehovah, or swears an oath to bind his soul with a bond, he shall not break his word. He shall do according to all that comes out of his mouth. 3 If a woman also vows a vow to Jehovah, and binds herself by a bond, being in her father's house in her youth, 4 and if her father hears her vow and her bond with which she has bound her soul, and if her father is silent as to her, then all her vows shall stand, and every bond with which she has bound her soul shall stand. 5 But if her father does not allow her in the day that he hears, not any of her vows or of her bonds with which she has bound her soul shall stand. And Jehovah shall forgive her because her father did not allow her.
