Numbers 30:9-16 - Vows Made By Widows
9 The vow of a widow and of her that is divorced, and all that they have bound their souls withal, shall stand in effect with them.
10 If she vowed in her husband's house or bound her soul with an oath, 11 and her husband heard it and held his peace and forbade her not: then all her vows and bonds wherewith she bound her soul, shall stand. 12 But if her husband disannulled them the same day that he heard them, then nothing that proceeded out of her lips in vows and bonds wherewith she bound her soul shall stand in effect: for her husband hath loosed them, and the LORD shall forgive her. 13 "All vows and oaths that bind to humble the soul, may her husband establish or break. 14 But if her husband hold his peace from one day unto another, then he establisheth all her vows and bonds which she had upon her, because he held his peace the same day that he heard them. 15 And if he afterward break them, he shall bear her sin himself."
16 These are the ordinances which the LORD commanded Moses, between a man and his wife, and between the father and his daughter, being a damsel in her father's house.
