Ecclesiastes 5:2-4

Young's Literal Translation

² Cause not thy mouth to hasten, and let not thy heart hasten to bring out a word before God, for God is in the heavens, and thou on the earth, therefore let thy words be few.

³ For the dream hath come by abundance of business, and the voice of a fool by abundance of words.

⁴ When thou vowest a vow to God, delay not to complete it, for there is no pleasure in fools; that which thou vowest -- complete.
