Mark 14:19

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

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

But, lo, the hand of him delivering me up is with me on the table,

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