(4) The sign of the prophet Jonas.--See Note on Matthew 12:39. As given by St. Mark, the answer was a more absolute refusal, "No sign" (i.e., none of the kind that was demanded) "shall be given to this generation."

Verse 4. - A wicked and adulterous generation... Jonas. These words our Lord had already uttered on a former occasion (Matthew 12:39), but he does not here explain them, as he did before (see Introduction, § 7). Under similar circumstances he repeats himself, but he wastes not time in useless discussions with perverse opponents who will not see the truth. Of his death and resurrection, whereof Jonah was a type, they knew and understood nothing. Perhaps they thought of Jonah only as a prophet against the heathen city Nineveh, and a preacher of repentance, and were disposed to resent the allusion as an affront to their vaunted righteousness. He left them. Took ship for Magedan, and crossed the lake to the northeast shore, in the neighbourhood of Bethsaida Julias. He, as it were, despaired of their improvement, and left them in righteous anger at their obduracy. "A man that is heretical after a first and second admonition refuse; knowing that such a one is perverted and sinneth, being self-condemned" (Titus 3:10, 11). Jesus never taught publicly or worked miracles again on this spot.

16:1-4 The Pharisees and Sadducees were opposed to each other in principles and in conduct; yet they joined against Christ. But they desired a sign of their own choosing: they despised those signs which relieved the necessity of the sick and sorrowful, and called for something else which would gratify the curiosity of the proud. It is great hypocrisy, when we slight the signs of God's ordaining, to seek for signs of our own devising.A wicked and adulterous generation,.... He says the same things here, as he did to the Pharisees on a like occasion, in Matthew 12:39.

And he left them; as persons hardened, perverse, and incurable, and as unworthy to be conversed with:

and departed: to the ship which brought him thither, and went in it to the other side of the sea of Galilee; see Mark 8:13.
