James 3:9

⁷  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:

⁸  But the tongue can no man tame; it is an unruly evil, full of deadly poison.

⁹  Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.

¹⁰  Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.

¹¹  Doth a fountain send forth at the same place sweet water and bitter?
