Luke 5:9

When Christ commanded to let down the nets, the multitude of the fishes taken was just as great as the Lord of the sea and land willed. For the voice of the Word is the voice of power, at whose bidding at the beginning of the world light and the other creatures came forth. At these things Peter wonders, for he was astonished, and all that were with him, &c.

Say thou also, Depart from me, for I am a sinful man, O Lord, that God may answer, Fear not. Confess thy sin, and the Lord will pardon thee. See how good the Lord is, who gives so much to men, that they have the power of making alive. As it follows, From henceforth thou shalt catch men.

Secondly there is added the admiration elevating to understanding, which was the reason for the humiliation in Peter. And he notes this when he says: For astonishment had surrounded him. In the surrounding is noted the vehemence of the astonishment: Isaiah 29, "Behold, I will proceed to do a marvelous thing among this people, a great and stupendous miracle." — And lest you believe that he alone marveled, but that others also were witnesses of the miracle, there is added: And all who were with him, at the catch of fish which they had taken, that is, on account of the great and unusual catch all marveled, according to that of the Psalm: "They who go down to the sea in ships," "they saw the works of the Lord and his wonders in the deep."
