Joh 2, Verses 23–25English original
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 Jesus did not commit himself unto them, because he knew all men. And needed not that any should testify of man: for he knew what was in man.
(Tr. xi. c. 2) The Maker knew better what was in His own work, than the work knew what was in itself. Peter knew not what was in himself when he said, I will go with Thee unto death; (Luke 22:33. ver. 61) but our Lord’s answer shewed that He knew what was in man; Before the cock crow, thou shalt thrice deny Me.
