4 But some one will reply, And why did he not find them, when the Lord had promised, saying, “Seek first the kingdom and righteousness of God, and all these things shall be added unto you”? Precisely also in this very way did the Lord fulfill His promise. For who else placed there the fishes that were to be caught, but He, who, we are bound to believe, threw them into the penury that compelled them to go a fishing, for no other reason than that He wished to show them the miracle He had prepared, that so He might both feed the preachers of His gospel, and at the same time enhance that gospel itself, by the great mystery which He was about to impress on their minds by the number of the fishes? And on this subject we also ought now to be telling you what He Himself has set before us.
5. “Simon Peter,” therefore, “says, I go a fishing.” Those who were with him “say unto him, We also go with you. And they went forth, and entered into a ship; and that night they caught nothing. But when the morning was now come, Jesus stood on the shore; but the disciples knew not that it was Jesus. Then Jesus says unto them, Children, have ye any meat? They answered Him, No. He says unto them, Cast the net on the right side of the ship, and you shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes. Therefore that disciple whom Jesus loved says unto Peter, It is the Lord. When Simon Peter heard that it was the Lord, he girt his coat unto him, for he was naked, and did cast himself into the sea. And the other disciples came in a little ship (for they were not far from the land, but as it were two hundred cubits), dragging the net with fishes. As soon then as they had come to land, they saw a fire of coals laid, and a fish laid thereon, and bread. Jesus says unto them, Bring of the fish which you have now caught. Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken.”
