Create a conceptual digital art illustration based on the biblical verse Luke 24:31 - 'And their eyes were opened, and they knew him; and he vanished out of their sight.' The scene should depict two people whose eyes are wide open in realization and knowledge, looking towards a direction where a figure, represented by a soft glow, is disappearing or dissipating. The setting should be ancient, perhaps Middle-Eastern architecture subtly hinted in the background. The overall tone should be filled with awe and wonder, with the color palette dominated by soft, ethereal hues.
