Exodus 12:30

“And Pharaoh rose up in the night, etc.] Being awakened by the uncommon noise he heard: he and all his servants, and all the Egyptians; he and his nobles, and ministers of state, courtiers, and counsellors, and his subjects in common, perhaps everywhere in his kingdom, but particularly in the metropolis: and there was a great cry in Egypt; throughout the whole land, the firstborn being everywhere slain, which caused a most dreadful lamentation of parents for their eldest son, of brethren and sisters for their elder brother, and of servants and maidens for the principal and heir of the family; a cry so loud and general as perhaps was never heard before or since, and under which distress they…”

“there was not a house where there was not one dead--Perhaps this statement is not to be taken absolutely. The Scriptures frequently use the words "all," "none," in a comparative sense--and so in this case.

What is to be understood is, that almost every house in Egypt had a death in it.”

“and there was a great cry: No people were more remarkable and frantic in their mournings than the Egyptians. When a relative died, every one left the house, and the women, with their hair loose, and their bosoms bare, ran wild about the street. The men also, with their apparel equally disordered, kept them company; all shrieking, howling, and beating themselves. What a scene of horror and distress must now have presented itself, when there was not a family in Egypt where there was not one dead! Exo 11:6; Pro 21:13; Amo 5:17; Mat 25:6; Jam 2:13 Exodus 12:31”
