Exodus 11:4-6

Complete Jewish Bible

(iv) ⁴ Moshe said, “Here is what Adonai says: ‘About midnight I will go out into Egypt, ⁵ and all the firstborn in the land of Egypt will die, from the firstborn of Pharaoh sitting on his throne to the firstborn of the slave-girl at the handmill, and all the firstborn of the livestock. ⁶ There will be a horrendous wailing throughout all the land of Egypt — there has never been another like it, and there never will be again.
