sat down with the twelve
The order of events on the night of the Passover supper appears to have been:
(1) The taking by our Lord and the disciples of their places at the table;
(2) the contention who should be greatest;
(3) the feet washing;
(4) the identification Judas as the traitor;
(5) the withdrawal of Judas;
(6) the institution of the supper;
(7) the words of Jesus while still in the room (Matthew 26:26-29); (Luke 22:35-38); (John 13:3-35); (Matthew 14:1-31).
(8) the words of Jesus between the room and the garden (Matthew 26:31-35); (Mark 14:26-31); (John 15:16); (John 15:17) it seems probable that the high-priestly prayer (John 17:1-26) was uttered after they reached the garden;
(9) the agony in the garden;
(10) the betrayal and arrest;
(11) Jesus before Caiaphas; Peter's denial.
