For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: He shows the unworthiness of such conduct from the dignity of the holy supper.
I - emphatic in the Greek. It is not my own, but the Lord's institution.
Received of the Lord - by immediate revelation from the risen Saviour (Galatians 1:12: cf. Acts 22:17-18; 2 Corinthians 12:1-4). х apo (G575), here, instead of para (G3844) (commonly used for immediate revelation), is to discriminate between Christ's personal appearance (Acts 9:1-43) and His revelation by His Spirit.] The renewal of the institution, by special revelation to Paul, enhances its solemnity. The similarity between Luke's and Paul's account of it implies that the former drew his information from the apostle, whose companion in travel he was. The undesigned coincidence is a proof of genuineness.
Night - the time for the Passover (Exodus 12:6): the time for the Lord's supper is not fixed.
Betrayed. With the traitor at the table, and though about to receive such injury from man, He gave this last gift, a pledge of His amazing love to man.
