Matthew 7:17-19

7:17 In the same way, every good tree bears good fruit, but the bad ¹  tree bears bad fruit. 7:18 A good tree is not able to bear bad fruit, nor a bad tree to bear good fruit. 7:19 Every tree that does not bear good fruit is cut down and thrown into the fire.

¹ tn Grk “rotten.” The word σαπρός, modifying “tree” in both v. 17 and 18, can also mean “diseased” (L&N 65.28).
