The Plague of Blood
This vignette artistically recreates a scene from The Prince of Egypt and the Old Testament, where Moses thrusts his staff into the Nile and, through the will of the God of the Israelites, turns the waters of the river into blood before Pharaoh's eyes.
"Moses did exactly what Adonai had ordered. He raised the staff and, in the sight of Pharaoh and his servants, struck the water in the river; and all the water in the river was turned into blood." —Exodus 7:20
