The Sign of Jonah38Then some of the Pharisees and teachers of the law said to him, “Teacher, we want to see a sign from you.” 39He answered, “A wicked and adulterous generation asks for a sign! But none will be given it except the sign of the prophet Jonah.40For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.
