Midrash su Deuteronomio 13:15

How did they examine the witnesses? It is written: Then thou shalt inquire, and make search, and ask diligently, and behold if it be true (Deut. 13:15). At the time they examined the witnesses concerning a sin an individual had committed, the Sanhedrin and all the Israelites would go out into the public square. They brought there the individual who had been charged with the offense which required stoning or one of the four death penalties that were imposed by the Beth Din. Two or three of the most distinguished leaders of the community would come forth and would question the witness. After they returned from the cross-examination, a member of the Sanhedrin would say to them: “What is your decision?” They would announce whether he was to live or to die. If he were to be sentenced to stoning, they would bring a pleasant-tasting but potent wine, and give it to him to drink so that he would not suffer pain from the stoning. Then the witnesses would come, bind his hands and feet, and place him where the stoning was to occur. The witnesses would then take a large stone, (large) enough to kill him, and would place it upon his heart. How did they place it on his heart? They did so simultaneously in order that no one of them might lower his portion of the stone before his companion.⁴And therefore be solely responsible for his death. They would place it on his heart together to conform to the verse: Thy hand shall be first upon him to put him to death (Deut. 13:10). After that all the Israelites were free to pelt him with stones. They did this to everyone condemned to death by the Beth Din.

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.
