Final answer:
The Pharaoh's magicians replicated the plagues of frogs and blood, according to the book of Exodus in the Bible.
Step-by-step explanation:
The two plagues that the Pharaoh's magicians replicated were frogs and blood. According to biblical accounts, specifically in the book of Exodus, the magicians of Egypt used their enchantments to mimic the plagues that Moses and Aaron brought forth upon Egypt by the will of God.
The purpose of these plagues was to compel the Pharaoh to release the Israelites from slavery. Although the magicians were able to replicate turning water into blood and causing frogs to overrun the land, they were unable to replicate the other plagues, which progressively grew more severe, culminating in the death of the firstborn sons of Egypt.
