Depict a scene based on the biblical narrative from Genesis 21:9. Show a woman of Middle-Eastern descent (Sarah) observing a young boy of Egyptian descent (Hagar's son) who she perceives to be jesting. This tableau should take the form of digital art, pulling in stylized elements such as smooth gradients, pixelation, and graphical imagery. The setting should be an ancient Middle-Eastern environment, honoring the historical context of the scene.
