Numbers 30:9-16 - Vows Made By Widows
9 But every vow of a widow and of her that is divorced, with which they have bound their souls, shall stand.
10 And if she vowed in her husband's house or bound her soul by a bond with an oath; 11 if her husband heard it and remained silent regarding it and did not disallow her, then all her vows shall stand, and every bond with which she bound her soul shall stand. 12 But if her husband has utterly made them void on the day he heard them, then whatever proceeded out of her lips concerning her vows or concerning the bond of her soul, shall not stand; her husband has made them void, and the LORD shall forgive her. 13 Every vow and every binding oath to afflict the soul, her husband may establish it, or her husband may make it void. 14 But if her husband remained silent regarding this from day to day; then he establishes all her vows or all her bonds, which are upon her; he confirms them because he remained silent regarding this in the day that he heard them. 15 But if he shall in any way make them void after that he has heard them, then he shall bear her iniquity.
16 These are the statutes which the LORD commanded Moses between a man and his wife and between the father and his daughter, being yet in her youth in her father's house.
