[SUP]Matthew 12 :40
38 [/SUP]Then certain of the scribes and of the Pharisees answered, saying, Master, we would see a sign from thee.
[SUP]39 [/SUP]But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:
[SUP]40 [/SUP]For as Jonas 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.
