³³ “Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit.^{(A) 34} You brood of vipers,^(B) how can you who are evil say anything good? For the mouth speaks^(C) what the heart is full of. ³⁵ A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him. ³⁶ But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken. ³⁷ For by your words you will be acquitted, and by your words you will be condemned.”^(D)

⁸ but no human being can tame the tongue. It is a restless evil, full of deadly poison.^(A)

⁹ With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness.^{(B) 10} Out of the same mouth come praise and cursing. My brothers and sisters, this should not be. ¹¹ Can both fresh water and salt water flow from the same spring? ¹² My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs?^(C) Neither can a salt spring produce fresh water.
