Midrash su Deuteronomio 13:16

Similarly, in the verse And he blotted out every living substance which was upon the face of the ground, both man and cattle (Gen. 7:3). He mentioned man first, because man was the first to sin, and after that he refers to beasts and creeping things. Likewise, since Scripture states: And they smote the men that were at the door with blindness, both small and great (ibid. 19:11), they smote the least important ones first and then the greater ones. Likewise, in accordance with the verse I will smite all the firstborn in the land of Egypt, both man and beast, man was punished first and then the beast. Another illustration is in the verse Thou shalt surely smite the inhabitants of that city with the edge of the sword (Deut. 13:16). He smote the inhabitants of the city with the sword, and then he slew the cattle. Similarly, And her belly shall swell (Num. 5:27) is followed by And her thighs shall fall away. That is, the part of the body that sinned first was punished first. Is it not logical to conclude that if retribution is exacted first from the one who commits an evil deed first, then the reward for good deeds, whose reward is far greater, is dispensed according to the same rule.

MISHNA: The men of a corrupt town have no share in the world to come, as it is said (Deut. 13, 14) There have gone forth men, Beliyaal, from the midst of thee, and have misled the inhabitants of their city (Fol. 112) Our Rabbis were taught concerning the verse: Devoting it utterly; this means to exclude the property of the righteous which is found out of town, and all that is therein, means to include the property of righteous which is inside the city. All the spoils, etc., includes the property of the guilty, which is [even] outside of the town. R. Simon says: "Why does the Torah say that the property of the righteous, which is inside the city, should be destroyed? Because what made them live in such a city? Was it not their property? Therefore it must be destroyed."

"and I shall smite": I might think, through an angel or through a messenger; it is, therefore, written (Ibid. 29) "and the L rd (Himself) smote every first-born" — not through an angel or a messenger. "and I smote every first born": even from different places. Whence do I derive (the same) even for the first-born of Egypt who were in other places? (From Psalms 136:10) "He smote Egypt through their first-born" (connoting, even if they were not in Egypt). Whence do I derive (the same for) the first-born of Cham and Cush? (viz. Genesis 10:6) From (Psalms 78:51) "And He struck every first-born in Egypt, the first fruit of their strength in the tents of Cham." "from man until beast": The initiator of the transgression was struck first. Similarly, (Genesis 7:23) "And all that existed on the face of the earth was blotted out — from man to beast, etc." Similarly, (Exodus 14:4) "And I will be honored through (the downfall of) Pharaoh and his entire host." Similarly, (Devarim 13:16) "Smite the inhabitants of that city … and its cattle." Similarly, (Numbers 5:27) "and her belly ('first in the transgression') will swell, and her thigh will fall." Here, too, "And I shall smite every first-born in the land of Egypt from man until beast." The initiator of the transgression was struck first. Now does this not follow a fortiori, viz.: If in His measure of punishment — the lesser (measure) — the initiator of the transgression is smitten first, how much more so in His measure of beneficence — the greater (measure) — (is the initiator of the mitzvah rewarded first)!
