John 13:21, 26, 30

Then Jesus was moved deeply in his spirit. Looking at his disciples, he announced, “I tell you the truth—one of you is about to betray me.”

“The one I give this piece of bread to after I’ve dipped it in the bowl,” Jesus replied. Then he dipped the piece of bread into the bowl and handed it to Judas Iscariot, the son of Simon.

So Judas left quickly and went out into the dark night to betray Jesus.
