Ecclesiastes 5:2-5

Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God; for God is in heaven, and thou upon earth: therefore let thy words be few. For a dream cometh with a multitude of business, and a fool’s voice with a multitude of words. When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou vowest. Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.
