And why even of yourselves, do you not judge that which is just?

'And why, also, of yourselves, judge ye not what is righteous?

"Why, too, do you not of yourselves arrive at just conclusions?

And why even of yourselves, etc.? Here Christ opens up the source of the evil, and, as it were, applies the lancet to the ulcer. He tells them that they do not descend into their consciences, and there examine with themselves, as in the presence of God, what is right. The reason why hypocrites are so much disposed to make objections is, that they throw their swelling words into the air without any concern, and never exercise calm thought, or place themselves at the tribunal of God, that the truth, when once ascertained, may be fully embraced. When Luke says that this was spoken to the multitudes, he does not contradict the narrative of Matthew and Mark; for it is probable that Christ adapted his style generally to the followers and disciples of the scribes, and to other despisers of God who resembled them, of whom he perceived that there were too many; as the present complaint or expostulation was applicable to the whole of that rabble.

And why - judge ye - Even without the express declarations of the prophets, ye might, from what ye see and hear yourselves, discern that God has now visited his people in such a manner as he never did before.

(15) Yea, and why even of yourselves judge ye not what is right?
(15) Men that are blinded with the love of themselves, and therefore are detestable and stubborn, will bear the punishment of their folly.

Yea, and why even of yourselves,.... From their own observation, as in discerning the signs of the weather; in a rational way, by the light of reason, and according to the dictates of their own consciences; by what they themselves saw and heard; by the signs and wonders which were done, they might have concluded, that now was the time of the Messiah's coming; and that he was come, and that Jesus of Nazareth was he: this was as easy, by observation, to be discerned, as the face of the sky was; even of themselves, without any hints or directions from others:
judge ye not what is right? or "truth", as the Syriac and Persic versions render it; concerning the present time, the coming of the Messiah, and the accomplishment of the promises and prophecies of the Old Testament in him: or why do ye not of yourselves judge, what is fit and right to be done between man and man, without going to law? and that, in cases which are plain and clear, the consequences of which may be as easily discerned, as what weather it will be by the signs in the heavens; to which sense the following words incline.

why even of yourselves, &c.--They might say, To do this requires more knowledge of Scripture and providence than we possess; but He sends them to their own conscience, as enough to show them who He was, and win them to immediate discipleship.

Why even of yourselves, without any external sign, judge ye not what is right? - Why do ye not discern and acknowledge the intrinsic excellence of my doctrine?
