Cast the net on the right side of the ship,— The disciples, not knowing Jesus, but imagining that he might be a person acquainted with the places proper for fishing, did as he directed, and caught a multitude of fishes. This was not merely a demonstration of the power of our Lord, but a kind of providential supply for his disciples and their families, which might be of service to them when they waited afterwards in Jerusalem, according to his order. See Luke 24:49. And it was likewise a sort of emblematical representation of the great success which should attend their endeavours to catch men in the net of the gospel. See Luke 5:9-10 and the Inferences on that chapter.
