[1] Let not many of you become teachers, my brethren, for you know that we who teach shall be judged with greater strictness. [2] 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. [3] If we put bits into the mouths of horses that they may obey us, we guide their whole bodies. [4] 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. [5] So the tongue is a little member and boasts of great things. How great a forest is set ablaze by a small fire! [6] 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. [7] For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by humankind, [8] but no human being can tame the tongue--a restless evil, full of deadly poison. [9] With it we bless the Lord and Father, and with it we curse men, who are made in the likeness of God. [10] From the same mouth come blessing and cursing. My brethren, this ought not to be so. [11] Does a spring pour forth from the same opening fresh water and brackish? [12] Can a fig tree, my brethren, yield olives, or a grapevine figs? No more can salt water yield fresh. [13] Who is wise and understanding among you? By his good life let him show his works in the meekness of wisdom. [14] But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. [15] This wisdom is not such as comes down from above, but is earthly, unspiritual, devilish. [16] For where jealousy and selfish ambition exist, there will be disorder and every vile practice. [17] But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, without uncertainty or insincerity. [18] And the harvest of righteousness is sown in peace by those who make peace.
