and her husband should hear it and say nothing to her, not forbidding her, all her vows and every pledge by which she has obligated herself will stand.
Whenever a man makes a vow to Adonai or swears an oath to obligate himself by a pledge, he is not to violate his word but do everything coming out of his mouth.
So her husband Elkanah said to her, “Do what seems best to you. Stay until you have weaned him—only may Adonai establish His word.” So the woman stayed home and nursed her son until she weaned him.
