34You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks.
35The good man out of his good treasure brings forth good things, and the evil man out of his evil treasure brings forth evil things.
36I tell you that every idle word that men speak, they will give account of it in the day of judgment.
37For by your words you will be justified, and by your words you will be condemned."
38Then certain of the scribes and Pharisees answered, saying, "Teacher, we want to see a sign from you."
39But he answered them, "An evil and adulterous generation seeks after a sign, and there will no sign be given it but the sign of Jonah, the prophet.
40For as Jonah was three days and three nights in the belly of the whale, so will the Son of Man be three days and three nights in the heart of the earth.
