Luke 22:23

And they began to question among themselves which of them it could be who was going to do such a thing.

In deep distress they began to ask him, each in turn, "It is not I, is it, Master?"

They began to be sorrowful and to say to him, one after another, "Surely, not I?"

Then the disciples began looking at one another, wondering which one of them he meant.
