Luke 22:49

they Specially Peter, but the Synoptists suppress his name from obviously prudential reasons which no longer existed when St John wrote.

Lord, shall we smite with the sword? Since it was illegal to carry swords on a feast-day, we have here another sign that the Last Supper had not been the Passover. The bringing of the sword was part of the misconception which Jesus had not cared further to remove at the supper; and if Judas had pressed into the enclosure they may have been entirely unaware as yet of the number of the captors. Future years would teach them that Christ's cause is served by dying, not by killing. The full reply of our Lord on this incident must be found by combining Matthew 26:53; John 18:10-11.
