Plagues of Egypt
In the Book of Exodus, the Plagues of Egypt (Hebrew: מכות מצרים) were ten disasters that Yahweh inflicted on the Egyptians to convince the Pharaoh to emancipate the enslaved Israelites, each of them confronting the Pharaoh and one of his Egyptian gods; they served as "signs and marvels" given by Yahweh in response to the Pharaoh's taunt that he did not know Yahweh: "The Egyptians shall know that I am the LORD". These Plagues are recited by Jews during the Passover Seder.
