Mark 8:17
Aware of their discussion, Jesus asked them: why are you talking about having no bread? Do you still not see or understand? Are your hearts hardened? — the diagnostic questions pile up: do you still not see, still not understand, still hardened hearts? The still communicates progressive failure — this is not the first opportunity to understand. The hard hearts (pepōrōmenēn kardian) explicitly applies to the disciples the same language used for Pharaoh (Exodus) and Jesus' enemies (Mark 3:5). The disciples' incomprehension is not merely intellectual slowness but a structural condition that will only be broken by the passion and resurrection.
