James 3:10

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

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

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

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

12Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
