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.
All Commentaries on Luke 11:29 Go To Luke 11

But the sign of Jonas. Instead of a prodigy in the heavens or in the air, I will give you one in the bosom of the earth, more wonderful than that of the prophet Jonas, who came out alive from the belly of the fish, which had swallowed him. Thus I will return alive from the bosom of the earth three days after my death. (Calmet)
He gave them a sign, not from heaven, for they were unworthy to behold it, but from the deep; the sign of his incarnation, not of his divinity; of his passion, not of his glory. (Ven. Bede)
