Ecclesiastes 5:1-5

Guard your steps as you go to the house of God, and approach to listen rather than to offer the sacrifice of fools; for they do not know that they are doing evil.

Do not be quick with your mouth or impulsive in thought to bring up a matter in the presence of God. For God is in heaven and you are on the earth; therefore let your words be few.

For the dream comes through much effort, and the voice of a fool through many words.

When you make a vow to God, do not be late in paying it; for He takes no delight in fools. Pay what you vow!

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