Ecclesiastes 5:2-6

King James Version

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

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

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

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

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