Luke 22:23

And they began to enquire among themselves which of them it was that should do this thing.

See Matthew 26:1; Mark 14:18. Jesus had just established and instituted the meal of His grace and kindness and salvation. But during all this time His betrayer also had his hand on the same table, the traitor had the effrontery to keep his position in the midst of the Twelve, known, in his boundless depravity, to the Lord alone. Even now the Lord gives him a warning; solemn, searching. The course of the Son of Man, the way in which He should fulfill the eternal counsel of God, had been arranged in all details: He must carry out this plan to its fulfillment. But it would be a sorry day and hour for him that was guilty of the terrible sin of the betrayal, of this basest, most heinous sin. Judas had better take another thought before it would be too late! The other disciples, indeed, were now filled with consternation and horror. They began earnestly to inquire and to search for him in their midst that would commit, that had determined within himself to perpetrate this unholy deed. Only Judas was so filled with Satan's wiles and power that it made little or no impression upon him. He may have thought that the Lord would have no difficulty in gaining His liberty, even if He should be in the hands of His enemies. That is a blindness, a hardening of the heart that plunges into everlasting damnation.
