8 But no one has ever been able to tame the tongue. It is evil and uncontrollable, full of deadly poison.
9 We use it to give thanks to our Lord and Father and also to curse other people, who are created in the likeness of God.
10 Words of thanksgiving and cursing pour out from the same mouth. My brothers and sisters, this should not happen!
11 No spring of water pours out sweet water and bitter water from the same opening.
12 A fig tree, my brothers and sisters, cannot bear olives; a grapevine cannot bear figs, nor can a salty spring produce sweet water.
13 Are there people among you who are wise and understanding? They are to prove it by their good lives, by their good deeds performed with humility and wisdom.
14 But if in your heart you are jealous, bitter, and selfish, don't sin against the truth by boasting of your wisdom.
