|Matthew Henry's Concise Commentary|
2:23-25 Our Lord knew all men, their nature, dispositions, affections, designs, so as we do not know any man, not even ourselves. He knows his crafty enemies, and all their secret projects; his false friends, and their true characters. He knows who are truly his, knows their uprightness, and knows their weaknesses. We know what is done by men; Christ knows what is in them, he tries the heart. Beware of a dead faith, or a formal profession: carnal, empty professors are not to be trusted, and however men impose on others or themselves, they cannot impose on the heart-searching God.
Gill's Exposition of the Entire Bible
And needed not that any should testify of man,.... Of this or the other man, that he was a good or a bad man; he needed no proofs to be made, or testimonies bore, or evidence given of men's characters and actions; he was of quick understanding, and could distinguish at once between a wicked man and a good man; and so had the characteristic which the Jews require of the Messiah; for they rejected Bar Cozba from being the Messiah, and slew him, because he could not smell, referring to Isaiah 11:3, or discern a bad man from a good man (n); but this Jesus could do, without any external evidence:
for he knew what was in man; which none but the spirit of a man can know; his inward thoughts, the secrets of the heart; thus Christ knew the thoughts of the Scribes and Pharisees, Matthew 9:4, being a discerner of the thoughts, and intents of the heart, Hebrews 4:12. This Apollonius Tyaneus, the ape of Christ, ascribed to himself (o); but is what is peculiar to God; and Christ being God, knows all that is in man; that there is no good in him naturally, nothing but what comes from his Father, is imparted by himself, or implanted by his Spirit; he knows the wickedness there is in man, that his heart is deceitful and desperately wicked, and full of all manner of iniquities; he knows in what condition all the and faculties of the souls of men are; what their affections are set upon, on earthly or heavenly things; whether there is any light in their understandings, or not; whether their wills are subdued and resigned to the will of God, or not; whether their minds and consciences are defiled, or their hearts are sprinkled from an evil conscience; in short, whether the internal good work of grace is begun upon their souls, or not; and he knows the secret springs of all actions, good and bad; all which prove his true and proper deity, and show him to be a suitable Saviour of sinners, and qualify him to be the Judge of the whole earth.

Jamieson-Fausset-Brown Bible Commentary
25. knew what was in man—It is impossible for language more clearly to assert of Christ what in Jer 17:9, 10, and elsewhere, is denied of all mere creatures.
