Proverbs 18:21 Death and life are in the power of the tongue, And those who love it and indulge it will eat its fruit and bear the consequences of their words. Isaiah 53:7 He was oppressed and He was afflicted,Yet He did not open His mouth [to complain or defend Himself]; Like a lamb that is led to the slaughter, And like a sheep that is silent before her shearers, So He did not open His mouth. Proverbs 13:3 The one who guards his mouth [thinking before he speaks] protects his life; The one who opens his lips wide [and chatters without thinking] comes to ruin. Psalm 34:13 Keep your tongue from evil, And your lips from speaking deceit. Read James 3:1-12 for more context.
