Matthew 12:38-40

RKJNT(i) 38 Then certain of the scribes and of the Pharisees answered, saying, Teacher, we wish see a sign from you. 39 But he answered them, An evil and adulterous generation seeks after a sign; and no sign shall be given to it, but the sign of the prophet Jonah: 40 For as Jonah was three days and three nights in the belly of a huge fish; so shall the Son of man be three days and three nights in the heart of the earth.
