Ecclesiastes 5:2, 6

Do not be hasty with your mouth [speaking careless words or vows] or impulsive in thought to bring up a matter before God. For God is in heaven and you are on earth; therefore let your words be few.

Do not allow your speech to cause you to sin, and do not say before the messenger (priest) of God that it was a mistake. Why should God be angry because of your voice (words) and destroy the work of your hands? [Mal 2:7]
