Numbers 30:2-4

New American Standard Bible

^2 (A)If a man makes a vow to the Lord, or takes an oath to ^[a]put himself under a binding obligation, he shall not break his word; he shall act in accordance with everything that comes out of his mouth.

³ “And if a woman makes a vow to the Lord, and puts herself under a binding obligation in her father’s house in her youth, ⁴ and her father hears her vow and her obligation under which she has put herself, and her father ^[b]says nothing to her, then all her vows shall ^[c]remain valid and every binding obligation under which she has put herself shall ^[d]remain valid.
