Numbers 30:11

Numbers 30 gives the law of vows, stating that a man who vows a vow or swears an oath to the Lord must not break his word but do all that proceeds from his mouth. For a young woman in her father's house or a married woman, her father or husband may disallow her vow on the day he hears it and it becomes void, but if he holds his peace the vow stands. The chapter closes by establishing these statutes governing vows between a man and his wife and between a father and his young daughter in his house.
