Numbers 30:2-5 If a man makes a vow to the LORD or swears an oath to obligate himself by a pledge, he must not break his word; he must do everything he has promised.

BSB⁽ⁱ⁾ ² If a man makes a vow to the LORD or swears an oath to obligate himself by a pledge, he must not break his word; he must do everything he has promised. ³ And if a woman in her father’s house during her youth 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 the vows or pledges by which she has bound herself shall stand. ⁵ But if her father prohibits her on the day he hears about it, then none of the vows or pledges by which she has bound herself shall stand. The LORD will absolve her because her father has prohibited her.
