34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart, the mouth speaketh.
35 A good man, out of the good treasure of the heart, bringeth forth good things: and an evil man, out of the evil treasure, bringeth forth evil things.
36 But I say to you, That for every idle word that men shall speak, they shall give account in the day of judgment.
37 For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
38 Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.
39 But he answered and said to them, An evil and adulterous generation seeketh for a sign, and there shall no sign be given to it, but the sign of the prophet Jonah.
40 For as Jonah was three days and three nights in the whale's belly: so shall the Son of man be three days and three nights in the heart of the earth.
