John 13:23

Most certainly I tell you, he who receives whomever I send, receives me; and he who receives me, receives him who sent me.”

When Jesus had said this, he was troubled in spirit, and testified, “Most certainly I tell you that one of you will betray me.”

The disciples looked at one another, perplexed about whom he spoke.

Simon Peter therefore beckoned to him, and said to him, “Tell us who it is of whom he speaks.”

He, leaning back, as he was, on Jesus’ chest, asked him, “Lord, who is it?”

Jesus therefore answered, “It is he to whom I will give this piece of bread when I have dipped it.” So when he had dipped the piece of bread, he gave it to Judas, the son of Simon Iscariot.
