Jesus saith unto them, Come and dine. — Comp. Note on John 21:15 and Luke 11:37, which are the only other instances of the verb in the New Testament. The meal referred to was the early morning meal which we call breakfast (John 21:4).
And none of the disciples durst ask him... — Comp. John 4:27. They approach Him in reverent silence. Knowing it is the Lord, they yet desire the assurance in His own words, and still they do not dare to ask, “Who art thou?” The Greek word rendered “ask” means to “prove” “inquire.” It is found elsewhere in the New Testament in Matthew 2:8; Matthew 10:11 only. The word rendered “durst,” is also not found again in St. John, but its use in the Gospels is — except in the instance of Nicodemus, “who went in boldly unto Pilate” (Mark 15:43) — confined to the expression of the reverence which dared not question our Lord. (Comp. Matthew 22:46; Mark 12:34; Luke 20:40.) In all these instances it is used with a negative, and with a verb of inquiry, as here.
