38 Then answered some of the scribes and Pharisees, saying: O teacher, we wish from thee a sign to see.

39 He but answering said to them: A generation evil and adulterous a sign demands; and a sign not shall be given to her, if not a sign of Jonas the prophet.

40 Like as for was Jonas in the belly of the fish three days and three nights; so shall be the son of the man in the heart of the earth three days and three nights.
