John Chrysostom
As the Lord sent the multitudes away after the miracle of the five loaves, so also now, not on foot, but by boat, that the multitudes may not follow Him; And he sent away the multitude, and entered into a ship, and came into the coasts of Magedan.
As then in the sky there is one sign of fair weather, and another of rain, so ought ye to think concerning me; now, in this My first coming, there is need of these signs which are done in the earth; but those which are done in heaven are reserved for the time of the second coming. Now I come as a physician, then as a judge; now I come in secret, then with much pomp, when the powers of the heavens shall be shaken. But now is not the time of these signs, now have I come to die, and to suffer humiliations; as it follows, An evil and adulterous generation seeketh after a sign, and there shall no sign be given it, but the sign of Jonas the prophet.
And when the Pharisees heard this, they ought to have asked Him, What it was He meant? But they had not asked at first with any desire of learning, and therefore the Lord leaves them, as it follows, And he left them, and went his way.
