Ah the power of Speech!  James Chapter 3 Verse7-12

“Every form of life, four-footed or winged crawling or swimming, can be tamed, and has been tamed by mankind;8The tongue no man can tame. It is a restless evil, full of deadly poison.9We use it to say,”Praised be the Lord and Father”, then we use it to curse men, though they are made in the likeness of God.10Blessing and curse come out of the same mouth. This ought not to be my brothers!11Does not a spring gush forth fresh water and foul from the same outlet?12A fig tree, brother, cannot produce olives, or grapevine figs; no more can a brackish source yield fresh water.”
