Ecclesiastes 5:2-6

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

³For a dream cometh through the multitude of business; and a fool's voice is known by a multitude of words.

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

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

⁶Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: why should God be angry at thy voice, and destroy the work of thy hands?
