Ecclesiastes 5:1-5

[1] Guard your steps when you go to the house of God; to draw near to listen is better than to offer the sacrifice of fools; for they do not know that they are doing evil.
[2] Be not rash with your mouth, nor let your heart be hasty to utter a word before God, for God is in heaven, and you upon earth; therefore let your words be few.
[3] For a dream comes with much business, and a fool's voice with many words.
[4] When you vow a vow to God, do not delay paying it; for he has no pleasure in fools. Pay what you vow.
[5] It is better that you should not vow than that you should vow and not pay.
