John Chrysostom
When he had bestowed sufficient favour upon the people by miracles, it was necessary for Him to depart. For miracles are always thought greater when the worker is gone, since they themselves are then the more heeded, and have in their turn a voice; as it is said, But when it was day, he departed, and went.
The Pharisees indeed, seeing how that the miracles themselves published His fame, were offended at His power. But the people hearing His words, assented and followed; as it is said, And the multitudes sought him, not indeed any of the chief priests, or scribes, but all those who had not been blackened with the dark stain of malice, and preserved their consciences unhurt.
Observe also, that He might, by abiding in the same place, have drawn all men over to Himself. He did not however do so, giving us an example to go about and seek those who are perishing, as the shepherd his lost sheep, and as the physician the sick. For by recovering one soul, we may be able to blot out a thousand sins. Hence also it follows, And he was preaching in the synagogues of Galilee. He frequently indeed went to the synagogues, to shew them that He was no deceiver. For if He were constantly to dwell in the desolate places, they would spread abroad that He was concealing Himself.
