Depict the dramatic scene from Exodus 7:12 'For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods.' Picture ancient men, of various descents like Caucasian, Middle-Eastern, and South Asian, each casting down his rod, transforming into a variety of serpents. Focus on the pivotal moment as Aaron's rod, turned into a grand serpent, engulfs the others. Capture it in a modern illustrative technique but refrain from any specific post-1912 art styles, let it rather resemble pre-20th century art, but transformed to digital format.
