Mark 14:10-11, 33

And Judas Iscariot, he that was one of the twelve, went away unto the chief priests, that he might deliver him unto them. And they, when they heard it, were glad, and promised to give him money. And he sought how he might conveniently deliver him unto them.

And he taketh with him Peter and James and John, and began to be greatly amazed, and sore troubled.
