Verses 1-7: The Plague of Frogs. God commands Moses to confront Pharaoh and demand Israel's release, threatening to cover Egypt with frogs if he refuses. Aaron stretches out his rod, and frogs infest the land, even appearing in Pharaoh's palace. Egyptian magicians replicate the plague, but Pharaoh soon begs Moses to pray for relief.
Verses 8-15: The Removal of Frogs and Pharaoh's Hardened Heart. Moses negotiates with Pharaoh for the frogs to be removed, and God grants this request. However, Pharaoh hardens his heart again, refusing to let the Israelites go.
Verses 16-19: The Plague of Lice. God instructs Aaron to strike the dust, turning it into lice that infest man and beast. Unlike the frogs, the magicians cannot replicate this plague and acknowledge it as the 'finger of God.' Yet Pharaoh remains obstinate.
Verses 20-32: The Plague of Flies and Pharaoh's Partial Concession. God warns Pharaoh of swarms of flies that will invade Egypt but spare Goshen, where the Israelites live. The flies come, causing great distress. Pharaoh offers a limited concession to allow sacrifices in the land, but Moses insists on a three-day journey into the wilderness. Pharaoh agrees but soon hardens his heart again after the flies are removed.
