Luke 22:23

And they inquired among themselves which of them it was who was about to do this.

And being grieved exceedingly, they each one began to say to him, Lord, is it I?

And they were sorry, and said to him, one by one, Is it I? And another, Is it I?

The disciples looked one on another, doubting of whom he spoke.
