Numbers 30:1-4 New International Version (NIV)

1. Moses said to the heads of the tribes of Israel: “This is what the Lord commands:

2. When a man makes a vow to the Lord or takes an oath to obligate himself by a pledge, he must not break his word but must do everything he said.

3. “When a young woman still living in her father’s household makes a vow to the Lord or obligates herself by a pledge

4. and her father hears about her vow or pledge but says nothing to her, then all her vows and every pledge by which she obligated herself will stand.
