Midrash sobre Exodo 9:3

Rabbi Levi said: Any place where [the phrase] “the hand of God” is stated, it is the plague of pestilence. The paradigm of them all is: “Behold, the hand of the Lord is [upon your cattle… a very severe pestilence]” (Exodus 9:3). Bar Kappara said: They demanded with the hand,¹¹⁴“Would that we had died by the hand of God in Egypt” (Exodus 16:3). and the hand¹¹⁵Regarding the generation of the wilderness, it is written: “And the hand of God was against them…until their demise” (Deuteronomy 2:14–15). harmed them. Rabbi Simon said: Among those who departed [the land of Israel] there was a plague;¹¹⁶This is derived from the fact that it states here: “The hand of the Lord has emerged against me [yatze’a bi],” which can be interpreted in the sense of biyatzi, “when I left.” among those who remained there was no plague. The students of Rabbi Neḥemya cite it from there: This is what is written: “Wherever they departed, the hand of the Lord was against them for evil” (Judges 2:15) – among those who departed there was a plague; among those who remained there was no plague. Rabbi Reuven said: Their children,¹¹⁷The children of those who departed Egypt. too, were suffering in their wake, and saying: ‘When will they die so we can enter the Land?’

They forced the Israelites to pasture their flocks, and so he sent the murrain against them, as it is said: Behold, the hand of the Lord is upon thy cattle (Exod. 9:3). They compelled the Israelites to keep the heated things warm, and so He afflicted them with boils. They plotted to have them stoned to death and so He sent hail upon them. They planned to make the Israelites their gardeners, and so He brought against them the locusts, which consumed their trees, and ate all the grass and fruit in the land. They conspired to imprison them, and so He brought darkness upon them. They planned to kill the Israelites, and so He smote all their firstborn. They wanted to drown them in water, and so He overthrew Pharaoh and his host in the Red Sea (Ps. 136:15).

And the Lord said unto Moses: “Rise up early in the morning, and stand before Pharaoh; lo, he cometh from the water” (Exod. 8:16). Why did Pharaoh go to the waters early in the morning? Because the wicked one boasted that since he was a god, he had no need to go to the water to relieve himself. Therefore he went out early in the morning so that no one would see him performing a demeaning act. That is why the Holy One, blessed be He, said to Moses: Rise up early in the morning, when he must (go out), and say unto him: Thus saith the Lord, the God of the Hebrews … for I will this time send all My plagues upon thy person, etc. (Exod. 9:14). Ordinarily, when a man desires to harm his enemy, he does so unexpectedly lest he be forewarned, but the Holy One, blessed be He, warned the wicked Pharaoh before each plague, as it is said: Behold, I will cause it to rain (ibid., v. 18), Behold, tomorrow will I bring locusts into thy border (ibid. 10:5). And He did so in each instance.
