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 Jonah the prophet.

Ephrem The Syrian
AD 373
The sign of Jonah served the Ninevites in two ways. If they would have rejected it, they would have gone down to Sheol alive like Jonah, but they were raised from the dead like him because they repented. Just as in the case of our Lord, who was set for the fall and the rising of many, people either lived through his being killed or died through his death…. They were asking him for a sign from heaven like thunder…. Jonah, after he went up from within the fish, was a negative sign to the Ninevites, because he proclaimed the destruction of their city. The disciples were also this way after the resurrection of our Lord. Commentary on Tatian’s Diatessaron
