Scale matters in apocalyptic theology. Targum Pseudo-Jonathan on Exodus 12:12 opens the heavens over Mizraim and reveals something the plain verse leaves hidden: the Lord descends to strike Egypt accompanied by "ninety thousand myriads of destroying angels." A myriad is ten thousand. Do the arithmetic and the count reaches nine hundred million angels — an army of such absurd size that no human enemy could imagine standing against it.
Then comes the four-part judgment on the idols of Egypt. The molten idols are melted. The stone idols are broken. The clay idols are shattered. The wooden idols are ground to dust. Each idol is destroyed by the treatment that its material most deserves — heat for metal, fracture for stone, impact for clay, pulverization for wood. The plague is not a blunt instrument. It reads the theological inventory of Egypt and undoes each piece with the fitting blow.
The rabbis understood this as the deeper meaning of the tenth plague. The firstborn are struck so that Egypt will grieve. The idols are struck so that Egypt will stop worshiping the things that deserved no worship. Only when the idols were gone could the Mizraee know, as the Targum says, that He is the Lord.
The enormous army of angels is there to make the moment overwhelming. The Lord of the world does not arrive quietly. When He appears in Egypt this night, the sky is full.
Takeaway: God's judgment is precise, not indiscriminate. Every false god of Egypt was undone in the way its own material best allowed.
