Comentario citado sobre Números 19:16

ויבאו שני המלאכים, “the two angels arrived, etc.;” Rashi points out that when these two individuals arrived in Eloney Mamre in front of Avraham’s tent, the Torah had referred to them as אנשים, men, mortal human beings, whereas now they are described as angels. If you were to counter that in the ensuing argument between the townspeople and Lot they are also described as אנשים, (verses 5,8,12) this sentence has to be understood as follows: “the ones whom the men of the city called אנשים, “men of substance, etc;” the whole dialogue must be understood thus:Alternately; Lot is saying to his fellow citizens: “do not do any harm to the guests in my house to whom you refer as אנשים. He realised that whereas he had recognised these individuals as angels, his fellow citizens obviously had not. This explanation is also applicable to verse 16, ויחזיקו האנשים, “the men” took hold of, etc.”

בנר שנטמא בטמא מת – this is a metallic candle and not of earthenware, for all utensils outside of earthenware utensils that came in contact with the defilement of the dead person become like it, it is principal level of impurity, it is a principle level of impurity, if it is a first level of impurity, it is a first level of impurity, as it is written (Numbers 19:16): “[And in the open, anyone who touches a person] who was killed [or died naturally, or human bone, or a grave, shall be impure seven days].” And they (i.e., the Rabbis) expound upon “who was killed” he is like someone who was slain, for the sword that had come in contact with the dead became like one of the original causes of Levitical uncleanness like the dead person himself. And when it had come in contact with something defiled by contact with the dead, which is a primary [cause of Levitical uncleanness], the sword also became a primary [cause of Levitical uncleanness], and all utensils are like a sword in the law, except for earthenware vessels. It is found that the metallic candle when it came in contact with something defiled by a dead person, it too became a primary [cause of Levitical] uncleanness. And now Rabbi Akiva adds on to the words of Rabbi Hanina the Assistant Priest, for Rabbi Hanina did not permit other than to restore something that had been third-level uncleanness to something second-level uncleanness. But Rabbi Akiva permitted restoring something that was third-level uncleanness to first level, for the oil that had been defiled by contact with a person who has ritually bathed but must wait for sunset to be perfectly clean, who is third-degree level of impurity, when they kindle it with a candle that had been defiled by contact with the dead, the candle itself becomes a primary form of Levitical uncleanness as we have stated and third-level [of impurity] returns to be first-level of impurity. And even though they did not prevent it, for since the title of impurity is upon it, we do not suspect him and it is permitted to add with his hands.

in einer Lampe. Aus Metall. Aus den Worten „בחלל חרב den Schwert-Erschlagenen“ in Num. 19, 16 wird die Lehre deduziert, dass das „Schwert“ dem „Erschlagenen“ gleich sei (חרב הרי הוא בחלל), d. h.: jedes Metallgerät, das eine Leiche oder einen an einer Leiche Verunreinigten (טמא מת) berührt, erhält denselben Unreinheitsgrad, wie ihn die Leiche oder der טמא מת besitzt, und es wird die Unreinheit nicht (wie bei Berührung anderer טומאות) um einen Grad abgeschwächt. Nach Maimonides u. A. findet diese Lehre nicht nur bei Metallgeräten Anwendung, sondern auch bei allen andern Geräten und Kleiderstoffen; ausgenommen sind bloß Tongeräte (כלי חרס).
