Jonah.

And when the people were gathered thick together, he began to say, This is an evil generation: they seek a sign; and there shall no sign be given it, but the sign of JONAS the prophet. For as JONAS was a sign unto the Ninevites, so shall also the Son of man be to this generation. ( Luke 11:29-30 )
