The plagues of Egypt are God’s demolition of an idolatrous nation. He turned the Nile to blood, defeating the god Hapi, and made the fertility goddess Heqet stink in piles of dead frogs. Now for the third, fourth, fifth and sixth plagues He sends gnats, flies, pestilence, and finally boils on men and beasts. Yahweh defeats the idols by these wonders, and by doing so He defeats them in hearts of His people.
