Guard your steps as you go to the house of God and draw near to listen rather than to offer the sacrifice of fools; for they do not know they are doing evil. Do not be hasty in word 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 should not vow than that you should vow and not pay.

Do not let your speech cause you to sin and do not say in the presence of the messenger of God that it was a mistake. Why should God be angry on account of your voice and destroy the work of your hands? For in many dreams and in many words there is emptiness. Rather, fear God.

[Ecclesiastes 5: 1-7—NASB]
