James 3:10 WBT

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

⁹  With this we bless God, even the Father; and with this we curse men, who 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?

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