Guard your steps when you go to the house of God; to draw near to listen is better than the sacrifice offered by fools; for they do not know how to keep from doing evil.
References for Ecclesiastes 5:1
Never be rash with your mouth, nor let your heart be quick to utter a word before God, for God is in heaven, and you upon earth; therefore let your words be few.
References for Ecclesiastes 5:2
For dreams come with many cares, and a fool's voice with many words.
When you make a vow to God, do not delay fulfilling it; for he has no pleasure in fools. Fulfill what you vow.
It is better that you should not vow than that you should vow and not fulfill it.
Do not let your mouth lead you into sin, and do not say before the messenger that it was a mistake; why should God be angry at your words, and destroy the work of your hands?
