When he was in Jerusalem, in the feast-day Or rather, during the feast, as εν τη εορτη, should undoubtedly be translated: that is, during all the days of the solemnity; many believed in his name Were inwardly persuaded that he was the Messiah, or, at least, that he was a teacher sent from God; when they saw the miracles which he did This, as well as John 3:2; John 4:45, plainly refers to some miracles wrought by Christ, the particulars of which are not transmitted to us. But Jesus did not commit himself unto them Did not repose such confidence in the sincerity of their profession of faith in him, or in their fidelity, courage, or wisdom, as to discover himself to be the Messiah. Because he knew all men Had perfect knowledge of their dispositions; and needed not that any should testify of man To give him any information concerning the character of any man, though ever so much a stranger to him; for he knew what was in man By an immediate and unerring penetration, he knew what was in the heart of every man; and consequently knew, that those people had such gross notions of the Messiah's kingdom, that there was no room for him to confide in them: or, he knew that the faith of many of them had not yet advanced to a full conviction; and foresaw that they would quickly fall off, when they found he was rejected by the great men, and did not erect a secular empire. Let us learn hence, not rashly to put ourselves into the power of others. Let us study a wise and happy medium, between universal suspiciousness, and that easiness and openness of temper which would make us the property of every pretender to kindness and respect.
