Matthew 16:4

Matthew 16:4.A wicked and adulterous nation. This passage was explained (426) under Matthew 12:38. The general meaning is, that the Jews are never satisfied with any signs, but are continually tickled by a wicked desire to tempt God. He does not call them an adulterous nation merely because they demand some kind of sign, (for the Lord sometimes permitted his people to do this,) but because they deliberately provoke God; and therefore he threatens that, after he has risen from the dead, he will be a prophet like Jonah. So Matthew at least says — for Mark does not mention Jonah — but the meaning is the same; for, strictly speaking, this was intended to serve as a sign to them, that Christ, when he had risen from the dead, would in every place cause the voice of his Gospel to be distinctly heard.
