James 3:3-18

Behold, we put bits in the horses' mouths, that
they may obey us; and we turn about their whole
body. Behold also the ships, which though they be
so great, and are driven of fierce winds, yet are
they turned about with a very small helm,
whithersoever the governor listeth. Even so the
tongue is a little member, and boasteth great
things. Behold, how great a matter a little fire
kindleth! And the tongue is a fire, a world of
iniquity: so is the tongue among our members, that
it defileth the whole body, and setteth on fire the
course of nature; and it is set on fire of hell. For
every kind of beasts, and of birds, and of serpents,
and of things in the sea, is tamed, and hath been
tamed of mankind: But the tongue can no man
tame; it is an unruly evil, full of deadly poison.
Therewith bless we God, even the Father; and
therewith curse we men, which are made after the
similitude of God. Out of the same mouth
proceedeth blessing and cursing. My brethren, these
things ought not so to be. Doth a fountain send
forth at the same place sweet water and bitter?
Can the fig tree, my brethren, bear olive berries?
either a vine, figs? so can no fountain both yield
salt water and fresh. Who is a wise man and
endued with knowledge among you? let him shew
out of a good conversation his works with
meekness of wisdom. But if ye have bitter envying
and strife in your hearts, glory not, and lie not
against the truth. This wisdom descendeth not
from above, but is earthly, sensual, devilish. For
where envying and strife is, there is confusion and
every evil work. But the wisdom that is from above
is first pure, then peaceable, gentle, and easy to be
intreated, full of mercy and good fruits, without
partiality, and without hypocrisy. And the fruit of
righteousness is sown in peace of them that make
peace.
