Context: In Chapters 13 through 16 of his Gospel John describes the events that took place in the Upper Room, immediately following the Last Supper. John's information, apparently, comes from an eyewitness who is probably the host. The account omits certain episodes, which probably occurred while he was absent checking on the movements of the authorities, or perhaps following Judas. For example, he does not mention the sacrament of the Last Supper. After the disciples have eaten their meal, Jesus washes their feet; this is an act of hospitality in a hot and dusty country and is customarily performed by a servant. Jesus thus humbles Himself as an example to His disciples; there have been signs of rivalry among them, and He wishes them to be reminded once more of the humility that must be theirs. Afterward He announces that one of those present will betray Him. Those present are reclining on couches about the table, and the eyewitness is close enough to Jesus that by leaning back he can speak to Him privately. At a sign from Peter he does so and asks Jesus who is the guilty man. It is customary to hand others morsels at table, and Jesus indicates that the next morsel He passes will go to the betrayer. The others present do not overhear the conversation between Jesus and the eyewitness: it is not recorded elsewhere in this circumstantial fashion. In any case, the culprit's identity will shortly be known to all. Jesus knows His disciples thoroughly, and what Judas has done is not something a weak character can successfully hide. He tells Judas to play out his part; Judas picks up the bag of money and leaves. It is probable that the witness follows him, to return only when the soldiers do; John does not describe the Agony in the Garden. The witness' account of what takes place immediately upon Jesus' announcement of betrayal is given below:
