1 Many have committed sin for gain, and those who seek to get rich will avert their eyes. 2 As a stake is driven firmly into a fissure between stones, so sin is wedged in between selling and buying. 3 If a person is not steadfast in the fear of the Lord, his house will be quickly overthrown. 4 When a sieve is shaken, the refuse appears; so do a person's faults when he speaks. 5 The kiln tests the potter's vessels; so the test of a person is in his conversation. 6 Its fruit discloses the cultivation of a tree; so a person's speech discloses the cultivation of his mind. 7 Do not praise anyone before he speaks, for this is the way people are tested.

15 “Watch out for false prophets, who come to you in sheep’s clothing but inwardly are voracious wolves. 16 You will recognize them by their fruit. Grapes are not gathered from thorns or figs from thistles, are they? 17 In the same way, every good tree bears good fruit, but the bad tree bears bad fruit. 18 A good tree is not able to bear bad fruit, nor a bad tree to bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 So then, you will recognize them by their fruit.
