30 Moses also gave the heads of the Israelite tribes these commands from the Lord:^[a]

Vows

² When a man makes a vow to the Lord or swears an oath to put himself under an obligation, he must not break his word. He must do everything that has come out of his mouth.

³ When a woman, while living in her father’s house during her youth, makes a vow to the Lord and puts herself under an obligation, ⁴ and her father hears about her vow and her obligation which she has undertaken, but her father says nothing to her, then all her vows will stand, and every obligation which she has undertaken will stand. ⁵ But if her father forbids her on the same day that he hears about them, none of her vows nor her obligations which she has undertaken will stand. The Lord will forgive her, because her father has forbidden her.

⁶ If she marries a husband while she is obligated by a vow or something she spoke rashly, ⁷ and her husband hears about it but says nothing to her on the same day that he hears about it, then her vows will stand, and her obligations which she has undertaken will be binding. ⁸ But if her husband forbids her on the same day that he hears about it, he will nullify her vow which obligates her and her responsibility for the things she spoke rashly. The Lord will forgive her.

⁹ But the vow of a widow or a divorced woman, every obligation which she put herself under, will be binding on her.

¹⁰ If, while she is still in her husband’s house, she took a vow or put herself under an obligation with an oath, ¹¹ and her husband hears about it but says nothing to her and does not forbid her, then all her vows will stand, and every obligation under which she has put herself will stand. ¹² But if her husband does indeed nullify them on the same day that he hears about them, then whatever came from her lips concerning her vows or her obligation will not stand. Her husband has nullified them. The Lord will forgive her.

¹³ Her husband may allow or nullify every vow or every oath in which she undertakes an obligation to deny herself.^{[b] 14} But if her husband indeed says nothing to her from day to day, then he confirms all her vows or all her obligations, which are binding on her. He has allowed them, because he said nothing to her on the day that he hears about them. ¹⁵ But if he nullifies them later than the day he hears about them, then he will bear her responsibility.

¹⁶ These are the statutes which the Lord commanded Moses about vows pertaining to a husband and his wife, or a father and his daughter during her youth while she still lives at her father’s house.
