Let not many of you become teachers, my brethren, for you know that we who teach shall be judged with greater strictness.
For we all make many mistakes, and if any one makes no mistakes in what he says he is a perfect man, able to bridle the whole body also.
If we put bits into the mouths of horses that they may obey us, we guide their whole bodies.
Look at the ships also; though they are so great and are driven by strong winds, they are guided by a very small rudder wherever the will of the pilot directs.
So the tongue is a little member and boasts of great things. How great a forest is set ablaze by a small fire!
And the tongue is a fire. The tongue is an unrighteous world among our members, staining the whole body, setting on fire the cycle of nature, and set on fire by hell.
For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by humankind,
but no human being can tame the tongue--a restless evil, full of deadly poison.
With it we bless the Lord and Father, and with it we curse men, who are made in the likeness of God.
From the same mouth come blessing and cursing. My brethren, this ought not to be so.
Does a spring pour forth from the same opening fresh water and brackish?
Can a fig tree, my brethren, yield olives, or a grapevine figs? No more can salt water yield fresh.
Who is wise and understanding among you? By his good life let him show his works in the meekness of wisdom.
But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth.
This wisdom is not such as comes down from above, but is earthly, unspiritual, devilish.
For where jealousy and selfish ambition exist, there will be disorder and every vile practice.
But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, without uncertainty or insincerity.
And the harvest of righteousness is sown in peace by those who make peace.
