James 3:7-11

For every species of beasts and birds, of reptiles and creatures of the sea, is tamed and has been tamed by the human race.

But no one among mankind can tame the tongue; it is a restless evil, full of deadly poison.

With it we bless our Lord and Father, and with it we curse people, who have been made in the likeness of God;

from the same mouth come both blessing and cursing. My brothers and sisters, these things should not be this way.

Does a spring send out from the same opening both fresh and bitter water?
