The ten plagues of Egypt are first described in which biblical book?

The Plagues of Egypt, in the story of the book of Exodus, are ten disasters inflicted on Biblical Egypt by the God of Israel in order to convince the Pharaoh to allow the Israelites to depart from slavery, 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 (god of the ancient Kingdom of Israel): "The Egyptians shall know that I am the Lord".

The 10 plagues in the book of Exodus:

01 Blood: The waters were turned to blood.

02 Frogs: Frogs swarmed forth, covering every inch of land.

03 Lice: All over Egypt, bugs crawled forth from the dust to cover the land.

04 Wild animals: Hordes of wild animals destroyed everything in their path.

05 Pestilence: A fatal pestilence killed most of the domestic animals.

06 Boils: The Pharaoh, his servants, the Egyptians and even their animals developed painful boils all over their bodies.

07 Fiery hail: Hail struck down all the crops in the fields and shattered every tree.

08 Locusts: The locusts covered the face of the land and swallowed up every crop and all the fruits of the trees.

09 Darkness: A thick darkness over the land of Egypt.

10 Death of the first-born: All firstborn Egyptian sons (and firstborn cattle) died.
