The night of the tenth plague was unlike anything Egypt had ever witnessed. Every firstborn in the land — from the heir of Pharaoh sitting on his throne to the firstborn of the captive languishing in the dungeon — was struck down in a single, terrible moment. But the Mekhilta raises a question that cuts to the heart of how God operates in the world: who actually carried out this devastating act?
One might naturally assume that God delegated. After all, the Torah is full of angels carrying out divine missions. An angel blocked Balaam's path. An angel struck the camp of Sennacherib. Surely God sent an angel or a messenger to handle the grim business of the tenth plague as well?
The Mekhilta says no. Emphatically no. The text of (Exodus 12:29) is precise: "And the Lord Himself smote every firstborn." Not through an angel. Not through a seraph. Not through any messenger whatsoever. God descended into Egypt — into the very heart of impurity — and personally struck every firstborn.
This is a staggering theological claim. The God who is beyond all comprehension, who dwells in unapproachable light, walked through the streets of Egypt that night like a warrior king who refuses to send soldiers when honor demands he fight himself. The Mekhilta is teaching that the Exodus was so foundational, so central to the identity of Israel, that God would entrust it to no one else. The plagues were not bureaucratic — they were personal.
