ISB ~ John 2 v25

he knew all men:The supernatural knowledge of Jesus is often highlighted in the Gospels (4:39; 16:30; Mt 9:4; 17:27; Mk 11:2-4; Lk 22:9-13). Here he detects deficient faith in those who marvel at his miracles but fail to grasp the significance of his mission. In the next episode, Nicodemus is representative of such inadequate belief (3:1-15) (CCC 473).
