The Plagues of Egypt (Biblical Hebrew: מכות מצרים), in the account of the Book of Exodus, are ten disasters inflicted on biblical Egypt by the God of Israel (Yahweh) in order to convince the Pharaoh to emancipate the enslaved Israelites, each of them confronting Pharaoh and one of his Egyptian gods; they serve as "signs and marvels" given by God to answer Pharaoh's taunt that he does not know Yahweh: "The Egyptians shall know that I am the LORD". The Ten Plagues are recited during the Passover Seder. They are in order: water turning to blood frogs lice flies or wild animals livestock pestilence boils hail locusts darkness the killing of firstborn children.
