Shemot 12:29-31

Orthodox Jewish Bible

²⁹ And it came to pass, that at midnight Hashem struck down kol bechor in Eretz Mitzrayim, from the bechor of Pharaoh sitting on his throne unto the bechor of the captive that was in the dungeon; and all the bechor behemah.

³⁰ And Pharaoh rose up in the lailah, he, and all his avadim, and kol Mitzrayim; and there was a tze’akah gedolah (great wail) in Mitzrayim; for there was not a bais where there was not one dead.

³¹ And he called for Moshe and Aharon by night, and said, Rise up, and get you forth, leave from among my people, both ye and the Bnei Yisroel; and go, serve Hashem, as ye have said.
