James 3:9-12

With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God. Out of the same mouth come both blessing and cursing. These things, my brothers, should not be this way [for we have a moral obligation to speak in a manner that reflects our fear of God and profound respect for His precepts]. Does a spring send out from the same opening both fresh and bitter water? Can a fig tree, my brothers, produce olives, or a grapevine produce figs? Nor can salt water produce fresh.
