Create a respectful, devotional scene inspired by Exodus 9:8 from the King James Version of the Bible, making vivid use of the medium and symbolic visuals typical of pre-1912 stained glass artistry. Illustrate Moses and Aaron, both depicted as Middle-Eastern men, taking handfuls of ashes from the furnace. Let Moses be sprinkling these ashes toward the heaven. Pharaoh, depicted as an Egyptian man, observes this scene. Despite this event taking place during a biblical plague, ensure the scene maintains its sacredness and reverence to Christianity. Do not include text or words.
