“And the Lord did so: and there came a grieuous swarme of flies into the house of Pharaoh, and into his seruants houses, and into all the lande of Egypt: the land was corrupted by reason of the swarme of flies.”
1611 King James Version (KJV)
8:24 There came a grievous swarm of flies - The prince of the power of the air has gloried in being Beel - zebub, the god of flies; but here it is proved that even in that he is a pretender, and an usurper; for even with swarms of flies God fights against his kingdom and prevails.
