רַבִּי יוֹסֵי הַגְּלִילִי RABBI Yossei HaGelili says: How can you know that the Egyptians were struck with ten plagues in Egypt and another fifty at the sea? For in Egypt it is said, “The astrologers said to Pharaoh, ‘This is the finger of God,’” while at the sea it is said, “When Israel saw the great hand the LORD raised against the Egyptians, the people feared the LORD, and they believed in the LORD and in His servant Moses.” If a finger struck them with ten plagues, conclude from this that THEY WERE STRUCK WITH TEN PLAGUES IN EGYPT AND WITH FIFTY PLAGUES AT THE SEA.

Rabbi Eliezer says: How can you know that each and every plague the Holy One brought upon the Egyptians in Egypt was in fact made up of four plagues? For it is said, “His fury was sent down upon them, great anger, rage, and distress, a company of messengers of destruction.” “Great anger” – one, “rage” – two, “distress” – three, “a company of messengers of destruction” – four. Conclude from this that THEY WERE STRUCK WITH FORTY PLAGUES IN EGYPT AND WITH TWO HUNDRED PLAGUES AT THE SEA.

Rabbi Akiva says: How can you know that each and every plague the Holy One brought upon the Egyptians in Egypt was in fact made up of five plagues? For it is said, “His fury was sent down upon them, great anger, rage, and distress, a company of messengers of destruction.” “His fury” – one, “great anger” – two, “rage” – three, “distress” – four, “a company of messengers of destruction” – five. Conclude from this that THEY WERE STRUCK WITH FIFTY PLAGUES IN EGYPT AND WITH TWO HUNDRED AND FIFTY PLAGUES AT THE SEA.
