God talks to Moses in the burning bush in the land of Midianites and gives him instructions to return to Egypt and talk to the new Pharaoh to free the Israelites. He takes Aaron with him. The new Pharaoh becomes stubborn as he refuses to follow Moses. Also, Moses clashes with the Pharaoh's magicians. Then, plagues starts to happen to Egypt as the river turns into blood, frogs come up on the land, gnats infest everything, flies are everywhere, the cattle die, boils come on the Egyptians' skin, hailstones (mixed with fire) come hurling down, locusts eat the crops, and darkness covers all Egypt. But in each of these, Israel is not affected by the Nine Plagues.
