'Vow to the Lord' in the Bible
So Israel made a vow to the Lord and said, "If you will indeed deliver this people into our hand, then we will utterly destroy their cities."
If a man makes a vow to the Lord or takes an oath of binding obligation on himself, he must not break his word, but must do whatever he has promised.
"If a young woman who is still living in her father's house makes a vow to the Lord or places herself under an obligation,
When you make a vow to the Lord your God you must not delay in fulfilling it, for otherwise he will surely hold you accountable as a sinner.
Jephthah made a vow to the Lord, saying, "If you really do hand the Ammonites over to me,
and how he made a vow to the Lord, and swore an oath to the powerful ruler of Jacob.
