One of You Will Betray Me
[21]After saying these things, Jesus was troubled in his spirit, and testified, "Truly, truly, I say to you, one of you will betray me." [22]The disciples looked at one another, uncertain of whom he spoke. [23]One of his disciples, whom Jesus loved, was reclining at table close to Jesus,(1) [24]so Simon Peter motioned to him to ask Jesus(2) of whom he was speaking. [25]So that disciple, leaning back against Jesus, said to him, "Lord, who is it?" [26]Jesus answered, "It is he to whom I will give this morsel of bread when I have dipped it." So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. [27]Then after he had taken the morsel, Satan entered into him. Jesus said to him, "What you are going to do, do quickly." [28]Now no one at the table knew why he said this to him. [29]Some thought that, because Judas had the moneybag, Jesus was telling him, "Buy what we need for the feast," or that he should give something to the poor. [30]So, after receiving the morsel of bread, he immediately went out. And it was night. (ESV)

The words had been there for a while now, growing stronger every day as He continued to choose to keep them in. Now, at what He knew would be their last meal together before everything changed, the words burst out, “I have something to tell you and I need you to know that it is true. One of you will betray me.”
He watched their eyes as they began to look around and whisper to each other. He saw that they had no comprehension of the level of betrayal that was coming.
He waited.
Peter was curious and bold, but still not bold enough to be the one to ask the question in front of everyone. He knew that open-hearted John didn’t care so much what the others thought. So Peter prodded John, who leaned in and asked, “Lord, who is it?” Jesus knew now was the time to tell them, but the coming betrayal was too painful. He could not say the words. Instead He replied to John, “I’ll show you.”
He grabbed a piece of the bread, the bread that He had just said represented His body, and He dipped in in the wine then reached across the table. For you, Judas, I am giving My body and My blood. No man takes My life, I give it freely. “Now go, and do your business quickly.”
