People can tame and already have tamed every kind of animal, bird, reptile, and fish. No one can tame the tongue, though. It is a restless evil, full of deadly poison. With it we both bless the Lord and Father and curse human beings made in God’s likeness. Blessing and cursing come from the same mouth. My brothers and sisters, it just shouldn’t be this way!
Both fresh water and salt water don’t come from the same spring, do they? My brothers and sisters, can a fig tree produce olives? Can a grapevine produce figs? Of course not, and fresh water doesn’t flow from a saltwater spring either.
