Ecclesiastes 5:2-5

²Don’t be rash with your mouth, and don’t let your heart be hasty to utter anything before God; for God is in heaven, and you on earth. Therefore let your words be few.

³For as a dream comes with a multitude of cares, so a fool’s speech with a multitude of words.

⁴When you vow a vow to God, don’t defer to pay it; for he has no pleasure in fools. Pay that which you vow.

⁵It is better that you should not vow, than that you should vow and not pay.
