His name is in their words. Rabbi Yudan bar Rabbi Simon said that the plagues were written on their bodies. Darkness was sent and it became dark. It is similar to Constantine, who went on a mission and burdened them excessively.
Similarly, darkness was sent and it did not fulfill its purpose. Their land was swarmed with frogs. Rabbi Yochanan said that wherever they sat, frogs would appear. You can say that in stone houses and book houses, they did not enter.
Rabbi Yishmael bar Rabbi Yosei said that this is one of the things that the Master requested gently. When the frog appeared, it would say, "I am the messenger of the one who said, 'Let there be a world and there was a world,' and the marble split apart from it, and it would go up," as it says, "And frogs and they destroyed them" (Psalms 78:45), like it says, "For their corruption is in them, they are blemished by them" (Leviticus 22:25). (He said, and the mixture will come).
He gave them rain with hail, and struck their vineyards and fig trees. Rabbi Huna said in the name of Rabbi Shimon ben Lakish, that this hail would come down on them like double-hailstones. Rabbi Yochanan said from Rabbi Shimon's words that when the vines were thin, the hail would come down like split ones. But for the fig trees, grace came and softened them, as it says, "And you shall plant them in their place" (Psalms 44:3).
He struck all the firstborn in their land. Rabbi Abba bar Kahana said, "The firstborn of a man, the firstborn of a woman, and the firstborn of an animal. And any household that did not have a firstborn, the appointed overseer who was there would kill them, and they would be redeemed with silver and gold." Rabbi Eliezer the Great said that the lowest of the Israelites took out of Egypt ninety donkeys loaded with silver and gold.
