Exodus 11:5-7

The Voice

⁵ and every firstborn son in every family in Egypt will die—from the firstborn of Pharaoh (who rules from his throne) to the firstborn of the slave girl (who grinds at the mill). The firstborn of all your cattle and livestock will die as well. ⁶ The air will be heavy with loud wailing throughout the land of Egypt, a deep and dismal mourning unlike any that has been or will ever be again in the land. ⁷ But among the people of Israel not even a dog’s bark will disturb the night. Then you will know that the Eternal makes a sharp distinction between Egypt and Israel.”
