“Death and life are in the power of the tongue, And those who love it will eat its fruit” (Proverbs 18.21)

“For out of the abundance of the heart the mouth speaks” (Luke 6.45)

Even so the tongue is a little member and boasts great things. See how great a forest a little fire kindles! And the tongue is a fire…” (James 3.5-6)

“We read that ‘out of the abundance of the heart the mouth speaks.’ This is a truth which is worthy of much thought. He who gives license to his tongue only discloses the contents of his own mind. By the excess of his words he proclaims his lack of discipline. By his very violence he shows his weakness” — Calvin Coolidge, September 21, 1924.
