Jesus saith unto them, Come and dine, х deute (G1205), aristeesate (G709)] - sweet familiarity, after such a manifestation of His command over the deep and its living contents!
And (or, 'But') none of the disciples durst ask him, Who art thou? knowing that it was the Lord - implying that they would have liked Him just to say, "It is I;" but having such convincing evidence, they were afraid of being "upbraided for their unbelief and hardness of heart" if they ventured to put the question.
