King James Bible
"Then the disciples looked one on another, doubting of whom he spake."
The disciples' exchanged glances reveal their collective bewilderment and attempt to read each other's faces for understanding. This occurs immediately after Jesus announces that one of them will betray him during the Last Supper, creating a moment of silent, visual communication among the confused group. Their uncertainty demonstrates both their inability to identify the betrayer and perhaps their struggle to believe any among them capable of such treachery. The Greek word for 'doubting' (aporeo) suggests being at a complete loss, highlighting how Jesus's shocking revelation has left them genuinely perplexed about which disciple he means.
