What is opened more times by mistake?

Someone once said, "Nothing is opened more times by mistake than the mouth." God's word has much to say about the tongue and mouth. For instance, "In the multitude of words there wanteth not sin..." Prov. 10:19. Another is, "He that keepeth his mouth keepeth his life: but he that openeth wide his lips shall have destruction." Prov. 13:3. One of my favorites is found in Prov. 21:23, "Whoso keepeth his mouth and his tongue keepeth his soul from troubles." And another one out of Prov. 16:23, "The heart of the wise teacheth his mouth, and added learnng to his lips".
Jesus said that out of the abundance of the heart the mouth speaketh. If we hide God's word in our hearts it will help keep us from sinning against God and our fellow man. In Prov. 15: 28, it says these words about the righteous man, "The heart of the righteous studieth to answer...", in the Amplified Bible, it says "ponders how to answer." All of our communications are important and should be approached humbly and with the fear of the Lord, for, "death and life are in the power of the tongue;..." Proverbs 18:21. Opened by mistake!!!
