Vows are not to be broken.
Numbers 30:1 And Moses spoke to the heads of the tribes of the children of Israel, saying, This is what Jehovah hath commanded. Numbers 30:2 If a man vow a vow to Jehovah, or swear an oath to bind his soul with a bond, he shall not break his word; according to all that hath gone out of his mouth shall he do.
The exception of a maid's vow,
Numbers 30:3 If a woman also vow a vow to Jehovah, and bind herself by a bond, in her father's house in her youth, Numbers 30:4 and her father hear her vow, and her bond wherewith she hath bound her soul, and her father shall be silent at her, then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand. Numbers 30:5 But if her father prohibited her in the day that he heard, none of her vows, or of her bonds wherewith she hath bound her soul, shall stand; and Jehovah shall pardon her, because her father prohibited her.
of a wife's,
Numbers 30:6 And if she have a husband, when she hath her vow upon her or ought that hath passed her lips wherewith she hath bound her soul, Numbers 30:7 and her husband hear it and be silent at her in the day that he heareth it, then her vows shall stand, and her bonds wherewith she bound her soul shall stand. Numbers 30:8 But if her husband prohibit her on the day that he heareth it, and annul her vow which is upon her, and what hath passed her lips, wherewith she hath bound her soul, then Jehovah shall pardon her.
of a widow's, or her that is divorced.
Numbers 30:9 But the vow of a widow, and of her that is divorced,everything wherewith she hath bound her soul shall stand against her. Numbers 30:10 And if she have vowed in her husband's house, or have bound her soul by an oath with a bond, Numbers 30:11 and her husband have heard it, and been silent at her, and hath not prohibited her, then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand. Numbers 30:12 But if her husband have expressly annulled them on the day that he heard them, then nothing of that which is gone out of her lips as to her vows or the bond on her soul, shall stand: her husband hath annulled them; and Jehovah will pardon her. Numbers 30:13 Every vow, and every binding oath to afflict the soul, her husband can establish it, or her husband can annul it. Numbers 30:14 And if her husband be altogether silent at her from day to day, then he hath established all her vows or all her bonds which are upon her; he hath confirmed them, for he hath been silent at her in the day that he heard them. Numbers 30:15 But if he in any way annul them after he hath heard them, then he shall bear her iniquity. Numbers 30:16 These are the statutes, which Jehovah commanded Moses, between a man and his wife, between a father and his daughter, in her youth in her father's house.
