James 3:3-11

Now if we put the horses’ bridles into their mouths that they may obey us, we turn about their whole body also. Behold, the ships also, though they are so great and are driven by rough winds, are yet turned about by a very small rudder, whither the impulse of the steersman willeth. So the tongue also is a little member, and boasteth great things. Behold, how much wood is kindled by how small a fire! And the tongue is a fire: the world of iniquity among our members is the tongue, which defileth the whole body, and setteth on fire the wheel of nature, and is set on fire by hell. For every kind of beasts and birds, of creeping things and things in the sea, is tamed, and hath been tamed by mankind: but the tongue can no man tame; it is a restless evil, it is full of deadly poison. Therewith bless we the Lord and Father; and therewith curse we men, who are made after the likeness of God: out of the same mouth cometh forth blessing and cursing. My brethren, these things ought not so to be. Doth the fountain send forth from the same opening sweet water and bitter?
