Ecclesiastes 5:1-2

1Guard your steps and focus on what you are doing as you go to the house of God and draw near to listen rather than to offer the [careless or irreverent] sacrifice of fools; for they are too ignorant to know they are doing evil.

2Do 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.
