And needed not that any should testify of man: for he knew what was in man.

John Chrysostom
AD 407
The meaning is of this kind. He who dwells in men's hearts, and enters into their thoughts, took no heed of outward words; and knowing well that their warmth was but for a season, He placed not confidence in them as in perfect disciples, nor committed all His doctrines to them as though they had already become firm believers. Now, to know what is in the heart of men belongs to God alone, who has fashioned hearts one by one Psalm 33:15, Septuagint, for, says Solomon, You, even Thou only, know the hearts 1 Kings 8:39; He therefore needed not witnesses to learn the thoughts of His own creatures, and so He felt no confidence in them because of their mere, temporary belief. Men, who know neither the present nor the future, often tell and entrust all without any reserve to persons who approach them deceitfully and who shortly will fall off from them; but Christ did not so, for well He knew all their secret thoughts.
And many such now there are, who have indeed the name of faith, but are unstable, and easily led away; wherefore neither now does Christ commit Himself to them, but conceals from them many things; and just as we do not place confidence in mere acquaintances but in real friends, so also does Christ. Hear what He says to His disciples, Henceforth I call you not servants, you are My friends. c. xv. 14, 15 Whence is this and why? Because all things that I have heard of My Father I have made known unto you. And therefore He gave no signs to the Jews who asked for them, because they asked tempting Him. Indeed the asking for signs is a practice of tempters both then and now; for even now there are some that seek them and say, Why do not miracles take place also at this present time? If you are faithful, as you ought to be, and lovest Christ as you ought to love Him, you have no need of signs, they are given to the unbelievers. How then, asks one, were they not given to the Jews? Given they certainly were; and if there were times when though they asked they did not receive them, it was because they asked them not that they might be delivered from their unbelief, but in order the more to confirm their wickedness.
