Mt. 12: 33-37: That which is in the heart can come to the surface only through lips. Jesus laid it down that a man would specially render account for his idle words. In public he carefully chooses what he says in private he takes the sentinels away. So whatever he says in anger what he really thinks and what he has often wanted to say, but which the cool control of prudence has kept him from saying. It is often these words which cause the greatest damage. A man may say in anger things he would never have said if he was in control of himself.
