Depict a scene inspired by Exodus 4:3 from the Old Testament. Render an aged man, represented as Moses, with distinct Middle Eastern characteristics, casting a staff onto the ground. The staff takes the form of a realistic serpent, causing the man to retreat in fear. This should all be set in a desert backdrop signifying the harsh conditions of the ancient Middle East. Style the image to emulate the attributes of digital art - using flat shapes, vibrant colors, and stylized outlines.
