33 “If you want good fruit, you must make the tree good. If your tree is not good, it will have bad fruit. A tree is known by the kind of fruit it produces.
34 You snakes! You are so evil. How can you say anything good? What people say with their mouths comes from what fills their hearts.
35 Those who are good have good things saved in their hearts. That’s why they say good things. But those who are evil have hearts full of evil, and that’s why they say things that are evil.
36 I tell you that everyone will have to answer for all the careless things they have said. This will happen on the day of judgment.
37 Your words will be used to judge you. What you have said will show whether you are right or whether you are guilty.”
38 Then some of the Pharisees and teachers of the law answered Jesus. They said, “Teacher, we want to see you do a miracle as a sign from God.”
39 Jesus answered, “Evil and sinful people are the ones who want to see a miracle as a sign. But no miracle will be done to prove anything to them. The only sign will be the miracle that happened to the prophet Jonah.
