This time? - Can ye not discover from the writings of the prophets, and from the events which now take place, that this is the time of the Messiah, and that I am the very person foretold by them?

Ye hypocrites,.... A word often used of the Scribes and Pharisees, and which suggests, that there were such in company, to whom Christ more especially directs his discourse; and this may be the rather thought, since much the like things are said by him to the Pharisees, with the Sadducees, in Matthew 16:1 and the same appellation is given them there, as here:
ye can discern the face of the sky, and of the earth; from the appearance of the sky, they could tell how it would be with the earth, and the inhabitants of it, whether they should have dry or wet weather, heat or cold:
but how is it that ye do not discern this time? that this is the time of the Messiah's coming, and that it is the accepted time, and day of salvation, if ye receive him, and believe in him; and a time of vengeance, if ye reject him: this might have been discerned by the prophecies of the Old Testament, which fix the characters of the Messiah, and the time of his coming; and describe the manners of the men of that generation, in which he should come: and point out both their happiness and their ruin; as also by the doctrines they heard Christ preach, and especially by the miracles which were wrought by him, it might have been known he was come.

how . . . not discern, &c.--unable to perceive what a critical period that was for the Jewish Church.

How do ye not discern this season - Of the Messiah's coming, distinguishable by so many surer signs.
