Ecclesiastes 5:2-6

²Be not hasty with thy mouth, and let not thy heart be swift 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 with much bustle, and a fool's voice with a multitude of words.

⁴When thou vowest a vow to God, delay 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 bring punishment on thy flesh, and say not before the angel, “It was a mistake.” Wherefore should God be angry on account of thy voice, and destroy the work of thy hands?
