“But Jesus did not commit himself unto them, because he knew all men,”
John 2:24 — Greek Interlinear
Church Fathers on John 2:24
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.
But how was it that many believed in Him from seeing His miracles? for he seems to have performed not supernatural works at Jerusalem, except we suppose Scripture to have passed them over. May not however the act of His making a scourge of small cords, and driving all out of the temple, be reckoned a miracle?
Those had been wiser disciples, however, who were brought to Christ not by His miracles, but by His doctrine. For it is the duller sort who are attracted by miracles; the more rational are convinced by prophecy, or doctrine. And therefore it follows, But Jesus did not commit Himself to them.
