Meanwhile, the Gospels of Matthew and Mark, while not documenting this particular exchange, inform us that the disciples were filled with sorrow and each approached Him with the question, "Is it I, Lord?" In response, Jesus stated, “He that putteth his hand in the dish with me, the same shall betray me." Additionally, Matthew records that Judas later questioned the Lord, "Am I not Rabbi?" to which Jesus affirmed his role.
The Gospel of John uniquely concludes this narrative, wherein John, reclining at Jesus' side, gestures to ask the Lord who the betrayer is, and receives the reply, “The one to whom I shall give a piece of bread after I have dipped it.” Clearly, the accounts from the Synoptic Gospels present varying details about this pivotal event. Luke, in a more condensed recounting, primarily focuses on the prophecy regarding the traitor, Christ's warning, and the disciples’ initial bewilderment and discussions. In contrast, Matthew and Mark highlight the subsequent inquiries from each disciple and offer an initial, vague indication of the betrayer, along with a caution extended to him. We can surmise that this warning was directed to Judas at the same moment John received his revelation.
Demonstrating a façade of courage, Judas posed the question to the Lord, "Is it I, Rabbi?" receiving a discreet acknowledgment in response. The other disciples likely did not hear this final exchange but interpreted the Lord's statement, “He who puts his hand in the dish with me,” as a general reference to one among the twelve, or as “the hand of him who betrays me at the table with me.” Subsequently, Peter gestures to John, urging him to inquire of Jesus regarding the identity of the traitor. If this inquiry occurred during the part of the Passover meal when the host was breaking bread and distributing it to the guests, it can be presumed that the identification of Judas transpired in this manner: Jesus responded to John, "He to whom I shall give a piece of bread after I have dipped it," indicating the very moment He was poised to hand a piece of bread to Judas. Judas, in a state of agitation and striving to conceal his inner turmoil, inadvertently reached for the dish prematurely, just as the Lord was placing His hand into it to offer the morsel intended for him.
