Shemot 11:4-6

Orthodox Jewish Bible

⁴ And Moshe said, Thus saith Hashem, About khatzot halailah (midnight) will I go out into the midst of Mitzrayim;

⁵ And all the bechor in Eretz Mitzrayim shall die, from the bechor Pharaoh that sitteth upon his kisse, even unto the bechor hashifchah that is behind the millstone; and all the bechor behemah.

⁶ And there shall be a great cry throughout kol Eretz Mitzrayim, such as there was none like it, nor shall be like it any more.
