John Chrysostom

Desiring to occasion a diligent examination of the things that had been done, He commanded those who had beheld the foregoing sign to be separated from Him; for even if He had continued present it would have been said that He had wrought the miracle fantastically, and not in verity; but it would never be urged against Him that He had done it in His absence; and therefore it is said, And straightway Jesus compelled his disciples to get into a ship, and to go before him to the other side, while he sent the multitudes away.
