Ecclesiastes 5:2-5

²Be not rash with thy mouth, and let not thy heart be hasty to utter anything before God: for God is in the heavens, and thou upon earth; therefore let thy words be few.

³For a dream cometh through the multitude of business, and a fool's voice through a multitude of words.

⁴When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed.

⁵Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.
