Achrei Mos -Till Death Do Us Part

(1) And the LORD spoke unto Moses, after the death of the two sons of Aaron, when they drew near before the LORD, and died; (2) and the LORD said unto Moses: ‘Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, before the ark-cover which is upon the ark; that he die not; for I appear in the cloudcloud upon the ark-cover.

(1) So he will not die, the way his sons did.

(2) For if he comes (into the Holy of Holies) he will die

(1) After Hashem cautioned the Jews so they wont die [see sub source 15:31], He said to Moshe, to warn Aaron as well so he won't die as his sons did. And this Parsha is a proof that Aaron sons brought a Ketores offering inside the curtain (in the Holy of Holies)

(1) Rabbi Eliezer said, the sons of Aaron died because they rendered a halachic decision in the presence of Moshe their teacher. Rabbi Yishmael said they entered the Temple while intoxicated, and the proof is that after their death the Torah warns against performing the service in the Temple while drunk.

(15) Another approach to the word וימותו focuses on the nature of these sons' deaths rather than on the fact of their deaths. The Torah writes: בקרבתם לפני השם, to describe that due to their love for G'd these people came too near the celestial source of light which has a deadly effect on man. This is the mystical dimension of what is commonly known as "death by Divine kiss," the kind of death experienced by both Aaron and Moses eventually. The deaths of Nadav and Avihu were similar to the death of all other completely righteous men. The only difference was that in the case of the deaths of people such as Moses and Aaron G'd's "kiss of death" approaches them, whereas in this case Nadav and Avihu approached "the kiss of death." (16) This is the meaning of the extra letter ו in בקרבתם לפני יקוק ו־ימותו. The Torah alludes to the fact that though these righteous people felt that they were approaching an area which would result in this "kiss of death" they did not flinch and kept getting closer. They attained a state of religious intoxication. The desire of their souls to fuse with the divine was so overpowering that they no longer made decisions in which their powers of conscious perception were involved. If we were to evaluate part of the emotional process these people underwent, perhaps the following may help. There are times when certain people feel such an overpowering hatred for someone that they will abandon all restraining influences in the desire to exercise their revenge even while they are subconsciously aware that they are forfeiting their very lives by the act of revenge. This may be the mystical dimension of what appears as licentious behaviour by prophets in Samuel I 19. There is a mystifying verse in Samuel I 19,24 which tells of Saul's pursuit of David and the religious experiences first experienced by the messengers despatched to capture David who at that time was in the proximity of the prophet Samuel and other prophets. All the messengers are reported as being overcome by an aura of religious experiences of these prophets. Eventually, the same happened to Saul himself. He is described as having divested himself of his clothing and remained naked [symbol of the desire to abandon the restrictions imposed on man by his body, Ed.] for a whole day in the presence of the prophet Samuel. Perhaps that verse affords us an inkling of the result of overpowering emotions of hatred. When we think of the other extreme of man's emotional range, his love for his source, i.e. his Creator, and the overpowering desire to be united with that source, we may have an inkling of what possessed Nadav and Avihu at the time. Basically speaking, we are dealing with the natural abhorrence each soul has for the need to be imprisoned inside a mere body. It is always the soul's desire to escape this body. Nadav and Avihu's souls experienced such an urge in an unusual manner. [At this point the author describes how a person may arrive at progressively purer insights due to his mind's ability to triumph over the impeding element of self, ego. Eventually, such a person will view "life" itself in an entirely new light such as hinted at by Moses in Deut. 30 19 when he exhorts the Jewish people to "choose life." The letter ב at the beginning of the word ב־חיים, is understood to refer to a life devoid of what he calls הרגש הכללי, emotions felt by all normal human beings. The author blesses the Lord for having granted selected individuals the ability to rise to such spiritual heights. Ed.]

(1) And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire therein, and laid incense thereon, and offered strange fire before the LORD, which He had not commanded them.
