Scenes from the Book of Exodus: The death of the firstborns (including the Pharaoh's son), and the Israelites leaving Egypt (Haggadah shel Pesaḥ, 1325–1374 CE, Barcelona via British Library)

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;[1] 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".[2]:117 These Plagues are recited by Jews during the Passover Seder.[3]

The consensus of modern scholars is that the Pentateuch does not give an accurate account of the origins of the Israelites.[4][5]:81[6]:6–7 Similarly, attempts to find natural explanations for the plagues (e.g., a volcanic eruption to explain the "darkness" plague) have been dismissed by biblical scholars on the grounds that their pattern, timing, rapid succession, and above all, control by Moses mark them as supernatural.[5]:90[2]:117–118

Plague One: The Nile to Blood

The Hebrew Bible's Book of Exodus says that Moses turned the Nile to blood by striking it with his staff. Pharaoh's magicians used their secret arts to also strike the Nile, creating a second layer of blood. In addition to the Nile, all water that was held in reserve, such as jars, was also transformed into blood. The Egyptians were forced to dig alongside the bank of the Nile, which still had pure water. One week passed before the plague dissipated.[3]
