'Vows' in the Bible

Thus says Yahweh of hosts, the God of Israel, {saying}, 'You and your wives have promised with your mouths and with your hands you have fulfilled, {saying}, "We certainly will carry out our vows that we vowed, to make smoke offerings to the queen of the heavens, and to pour out to her libations." You must certainly keep your vows and you must certainly carry out your vows.'
