Exodus 11:4-6

Douay-Rheims 1899 American Edition

⁴ And he said: Thus said the Lord: At midnight I will enter into Egypt.

⁵ And every firstborn in the land of the Egyptians shall die, from the firstborn of Pharao who sitteth on his throne, even to the first born of the handmaid that is at the mill, and all the firstborn of beasts.

⁶ And there shall be a great cry in all the land of Egypt, such as neither hath been before, nor shall be hereafter.
