And the Jews wondered Those who think that Christ was received in such a manner as to be esteemed and honored are mistaken; for the wonder or astonishment of the Jews is of such a nature, that they seek occasion from it to despise him. For such is the ingratitude of men that, in judging of the works of God, they always seek deliberately an occasion of falling into error. If God acts by the usual means and in the ordinary way, those means which are visible to the eyes are -- as it were -- veils which hinder us from perceiving the Divine hand; and therefore we discern nothing in them but what is human. But if an unwonted power of God shines above the order of nature and the means generally known, we are stunned; and what ought to have deeply affected all our senses passes away as a dream. For such is our pride, that we take no interest in any thing of which we do not know the reason. How doth this man know letters? It was an astonishing proof of the power and grace of God, that Christ, who had not been taught by any master, was yet eminently distinguished by his knowledge of the Scriptures; and that he, who had never been a scholar, should be a most excellent teacher and instructor. But for this very reason the Jews despise the grace of God, because it exceeds their capacity. Admonished by their example, therefore, let us learn to exercise deeper reverence for God than we are wont to do in the consideration of his works.

Knoweth this man letters - The Jewish letters or science consisted in the knowledge of their Scriptures and traditions. Jesus exhibited in his discourses such a profound acquaintance with the Old Testament as to excite their amazement and admiration.
Having never learned - The Jews taught their law and tradition in celebrated schools. As Jesus had not been instructed in those schools, they were amazed at his learning. What early human teaching the Saviour had we have no means of ascertaining, further than that it was customary for the Jews to teach their children to read the Scriptures. 2-Timothy 3:15; "from a child thou (Timothy) hast known the holy scriptures."

How knoweth this man letters, having never learned? - The Jewish learning consisted in the knowledge of their own scriptures, and the traditions of their elders. In this learning our blessed Lord excelled. No person ever spoke with more grace and dignity, or knew better how to make a more proper use, or a happier application, of Jewish allegories and parables; because none ever penetrated the sense of the Scriptures as he did; none ever cited them more successfully, or ever showed their accomplishment in so complete and satisfactory a manner. As these branches of learning were taught at the Jewish schools, and our Lord had never attended there, they were astonished to find him excelling in that sort of learning, of which they themselves professed to be the sole teachers.

And the Jews marvelled,.... Both at the matter, and manner of his doctrine; it was such, as never man spake; his words were so gracious, and there were such truth and evidence in them, and they were delivered with such power and authority, that they were astonished at them:
saying, how knoweth this man letters? or "the Scriptures", as the Arabic and Persic versions render it; which are called "holy letters", 2-Timothy 3:15; according to which, the sense is, that they were surprised at his knowledge of the Scriptures, that he should be conversant with them, and be able to interpret them, and give the sense and meaning of them, in so full and clear a manner, as he did: or else the sense is, how came this man to be such a learned man? whence has he this wisdom, and all this learning which he shows? as in Matthew 13:54. So a learned man is in Isaiah 29:11, said to be one that , , "knows letters", as the Septuagint there translate the Hebrew text; but how Christ should know them, or be a learned man,
having never learned, was surprising to them: that is, he had not had a liberal education, but was brought up to a trade; he was not trained up at the feet of any of their Rabbins, in any of their universities, or schools of learning; and in which they were certainly right. Modern Jews pretend to say he had a master, whom they sometimes call Elchanan (o), but most commonly they make him to be R. Joshua ben Perachiah (p): with whom they say, he fled into Alexandria in Egypt, for fear of Jannai the king: and one of their writers (q), on this account, charges the evangelist with a falsehood: but who are we to believe, the Jews who lived at the same time with Jesus, and knew his education and manner of life, or those that have lived ages since?
(o) Toldos Jesu, p. 5. (p) Juchasin, fol. 159. 1. Ganz Tzemach David, par. 1, fol. 21. 1. & 24. (q) R. Isaac Chizzuk Emuna, par. 2. c. 46. p. 435.

How knoweth . . . letters--learning (Acts 26:24).
having never learned--at any rabbinical school, as Paul under Gamaliel. These rulers knew well enough that He had not studied under any human teacher--an important admission against ancient and modern attempts to trace our Lord's wisdom to human sources [MEYER]. Probably His teaching on this occasion was expository, manifesting that unrivalled faculty and depth which in the Sermon on the Mount had excited the astonishment of all.

How knoweth, etc.? The Jewish rulers were astonished at his learning, since he had never attended the great schools of their doctors.

How does this man know letters, having never learned? - How comes he to be so well acquainted with sacred literature as to be able thus to expound the Scripture, with such propriety and gracefulness, seeing he has never learned this, at any place of education?
