Illustrate a symbolic depiction of Matthew 22:7 - 'But when the king heard thereof, he was angered: and he dispatched his forces, and eliminated those offenders, and set their city aflame.' This image needs to respect the context of the Bible verse. The style should be reminiscent of digital art, focusing on the vivid contrasts between dark shadows and bright colors and the crisp clarity of lines that this medium allows. Pay particular attention to conveying symbolism appropriately, using allegorical figures to represent the king, his forces, the offenders, and the city.
