John 2:23

Of the men of that time some clung to their error, others laid hold on the truth, while of these last, some having retained it for a little while again fell off from it. Alluding to these, Christ compared them to seeds not deeply sown, but having their roots upon the surface of the earth; and He said that they should quickly perish. And these the Evangelist has here pointed out to us, saying, "When He was in Jerusalem, at the Passover, in the feast, many believed on Him, when they saw the miracles which He did." "But Jesus did not commit Himself unto them." For they were the more perfect among His disciples, who came to Him not only because of His miracles, but through His teaching also. The grosser sort the miracles attracted, but the better reasoners His prophecies and doctrines; and so they who were taken by His teaching were more steadfast than those attracted by His miracles. And Christ also called them "blessed," saying, "Blessed are they that have not seen, and yet have believed." But that these here mentioned were not real disciples, the following passage shows, for it saith, "Jesus did not commit Himself unto them." Wherefore? "Because He knew all things," "And needed not that any should testify of man, for He knew what was in man." The meaning is of this kind. […]

But it is greatly to be wondered at, how it has come to pass that, while affirming that they have found out the mysteries of God, they have not examined the Gospels to ascertain how often after His baptism the Lord went up, at the time of the passover, to Jerusalem, in accordance with what was the practice of the Jews from every land, and every year, that they should assemble at this period in Jerusalem, and there celebrate the feast of the passover. First of all, after He had made the water wine at Cana of Galilee, He went up to the festival day of the passover, on which occasion it is written, "For many believed in Him, when they saw the signs which He did," as John the disciple of the Lord records.

When Jesus was at the feast, some apparently believed in His name; but their faith was unsteady. For, attending to Christ for a time not as God, but as a God-bearing man, they again fell away even from this most insignificant faith. And that they …

When he was in Jerusalem. Here is touched upon the building up of the faith of the Jews at the sight of signs of power. For it must be understood that he did many things, although the Evangelist did not describe them, as Chrysostom says. …

(in loc.) The Evangelist has related above what our Lord did on his way to Jerusalem; now He relates how others were affected towards Him at Jerusalem; Now when He was in Jerusalem at the Passover, in the feast day, many believed in His Name, when they saw the miracles which He did.

Then he sets forth the fruit which resulted from the signs, namely, the conversion of certain believers. Concerning this he does three things. First, he mentions those who believed on account of the miracles. Secondly, he shows the attitude of Christ to them (v 24). …

Now when he was in Jerusalem at the passover,....

Note, [1.] Those that follow Christ shall feast with him, they shall fare as he fares, so he has bespoken for them ( ch. xii. 26 ): Where I am, there shall my servant be also. [2.] Love to Christ is testified by a love to those that are his, for his sake; our goodness extendeth not to him, but to the saints.

The second miracle which our Lord is recorded to have wrought demands our attention in these verses. Like the first miracle at Cana, it is eminently typical and significant of things yet to come. To attend a marriage feast, and cleanse the temple from profanation were among the first acts of our Lord's ministry at His first coming. To purify the whole visible Church, and hold a marriage supper, will be among His first acts, when He comes again. We see, for one thing, in this passage, how much Christ disapproves all irreverent behavior in the house of God .

To purify the whole visible Church, and hold a marriage supper, will be among His first acts, when He comes again. We see, for one thing, in this passage, how much Christ disapproves all irreverent behavior in the house of God . We are told that He drove out of the temple those whom He found selling oxen and sheep and doves within its walls—that He poured out the changers' money and overthrew their tables—and that He said to those who sold doves, "Take these things away from here! Do not make my Father’s house a marketplace!" On no occasion in our Lord's earthly ministry do we find Him acting so energetically, and exhibiting such righteous indignation, as on the occasion now before us. Nothing seems to have called from Him such a marked display of holy wrath as the gross irreverence which the priests permitted in the temple, notwithstanding all their boasted zeal for God's law. Twice, it will be remembered, He discovered the same profanation of His Father's house going on, within three years, once at the beginning of His ministry and once at the end. Twice we see Him expressing his displeasure in the strongest terms. "The thing is doubled" in order to impress a lesson more strongly on our minds. The passage is one that ought to raise deep searchings of heart in many quarters. Are there none who profess and call themselves Christians, behaving every Sunday just as badly as these Jews? Are there none who secretly bring into the house of God their money, their lands, their houses, their cattle, and a whole train of worldly affairs?

Many believed in his name - They believed him to be the promised Messiah, but did not believe in him to the salvation of their souls: for we find, from the following verse, that their hearts were not at all changed, because our blessed Lord could not trust himself to them.
