Chapter 7 of Exodus begins the series of confrontations between God and Pharaoh through Moses and Aaron. In this chapter, God demonstrates His authority through miraculous signs and the first plague upon Egypt, showing that His power surpasses that of Egypt and its rulers.
God Strengthens Moses’ Role
God instructs Moses and Aaron about how they will approach Pharaoh.
- God tells Moses that he will be like God to Pharaoh, while Aaron will serve as his spokesman
- Moses will receive God’s commands, and Aaron will communicate them to Pharaoh
- Pharaoh will initially refuse to release the Israelites
God explains that this resistance will allow Him to display His power through mighty acts and judgments against Egypt, ultimately leading to Israel’s deliverance.
Aaron’s Staff Becomes a Serpent
Moses and Aaron go before Pharaoh and present the sign God instructed them to perform.
- Aaron throws his staff before Pharaoh, and it becomes a serpent
- Pharaoh responds by calling his magicians and wise men, who replicate the same sign through their secret arts
However, Aaron’s serpent swallows the serpents of the Egyptian magicians, demonstrating the superiority of God’s power.
Despite this sign, Pharaoh’s heart remains hardened, and he refuses to listen.
The First Plague: Water Turned to Blood
God instructs Moses to confront Pharaoh again by the Nile River.
Through Aaron, God performs a powerful sign:
- Aaron stretches out his staff over the waters of Egypt
- The waters of the Nile turn into blood
- Fish in the river die, and the river begins to smell
- The Egyptians can no longer drink water from the Nile
This plague affects not only the Nile but also canals, ponds, and containers of water throughout Egypt.
The Response of Pharaoh
The Egyptian magicians again attempt to imitate the sign by turning water into blood.
Because of this, Pharaoh’s heart remains hardened, and he refuses to release the Israelites.
Instead of responding to the disaster, Pharaoh returns to his palace, ignoring the suffering of his people.
Meanwhile, the Egyptians begin digging along the Nile to find drinkable water, since the river has been contaminated.
The plague continues for seven days.
