The Evangelist alludes to himself here the same way he always does. He recognised our Lord either by the miracle, or by the sound of His voice, or the association of former occasions on which He found them fishing. Peter was naked in comparison with the usual dress he wore, in the sense in which we say to a person whom we meet thinly clad, You are quite bare. Peter was hare for convenience sake, as fishermen are in fishing.
