Luke 22:23

And they began to reason among themselves, who then of them it may be, who is about to do this thing.

And being grieved exceedingly, they began to say to him, each of them, 'Is it I, Sir?'

And they began to be sorrowful, and to say to him, one by one, 'Is it I?' and another, 'Is it I?'

the disciples were looking, therefore, one at another, doubting concerning whom he speaketh.
