The Be'er Yosef in Parshas Masei quotes the Arizal's Shaar HaMitzvos parshas Shoftim as follows:

‏ ...הרג את המצרי שהוא קין, היה שוגג, כי הוא חשב שהדין עמו על שהרג הבל, ולכן הרגו בשם המפורש כדי לתקן ע"י שם מ"ב וכו' אמנם חטא בזה כנז' בר"מ פ' משפטים

[Moshe] killed the Egyptian who was Kayin (a gilgul?), [and was therefore considered] a shogeg, since he thought he was justified, due to [Kayin's] murder of Hevel. Therefore [Moshe] killed [the Egyptian] with the explicit name in order to rectify [his soul] using the 42 letter name... however he sinned with this, as mentioned by R"M parshas Mishpatim.

Who is ר"מ, what was Moshe's sin, and why is he considered shogeg?

(The Be'er Yosef brings earlier from the Shaar Hapesukim parshas Mishpatim that he was considered shogeg since his intention was to correct his soul by killing him with the explicit name, still unclear why that is)

  • Well, no one was supposed to kill Kayin, right? Consider Lamech.

  • -1 because you clearly didn't read the paragraph before or after the one you quoted. The one before it explains the R"M's statement (and has its name), and the one after quotes the R"M (also by name) directly. Commented Feb 7, 2018 at 19:33

    @רבות מחשבות I think it's rather presumptuous I didn't read the paragraph before or after. I didn't see the Raya mehemnah mention that moshe sinned, and still don't, so I didn't put two and two together that RM = Raya mehemnah. Regardless if it does or not, it doesn't answer my other questions.

  • @robev I deeply apologize. I would like to give you a Beracha (as I was Choshed a Kasher): May you be Zocheh to a long and healthy life, and keep up your Milchamta Shel Torah! Commented Feb 7, 2018 at 20:35

1 Answer 1


As it says directly in the link you provided (bottom right paragraph, Dibur Hamaschil Vihinei Beshaar), it is the Zohar in the R"M = Raaya Mehemna, Parshas Mishpatim.

That paragraph explains the background as well. For those interested in reading the Raaya Mehemna, it is the paragraph on the bottom left of the linked paper.

Edit: Apparently it is still unclear, so here is a rough translation from the previous paragraph and what it says:

...With this introduction, these Pesukim can be explained, when they say "He who hits a man and he dies" (מכה איש ומת מות יומת, which is an Aveirah that is punishable by death), this refers to Moshe Rabbeinu, who killed the Mitzri called "ISH Mitzri", and if this would have been purposeful, his judgment should have been to be killed. However, since the purpose of the intention of Moshe was to help and fix his Neshama by killing him with the Shem Hameforash, if so, he killed him Beshogeg (i.e. since his intentions were for good, even though he killed him, it is not punishable by death, rather by Galus), and this is why it continues "Vaasher Lo Tzadah", which refers to Moshe...

  • Oh I didn't realize that's what it stood for. although the quote he brings from it doesn't mention a sin, from what I can see

  • @robev yes he does, Moshe is considered a Rotzeach Beshogeg, which is why Hashem says Vesamti Lecha Makom. He also says why he is considered a shogeg. Please read the full paragraph. Commented Feb 7, 2018 at 19:27
  • The pasuk says he killed the mitzri, all the Raya mehemnah says is he was chayiv galus. How does that necessarily follow he was חטא? It doesn't say he was a shogeg or why it would be true.

  • @robev Well, Galus is for those who were חוטא בשוגג.

    Instead of writing a new answer which only addresses my problem of good intentions making someone a shogeg, since you answered the other issues I'll accept this as correct. For some sources on good intentions making someone a shogeg and chayav galus, see טעה בדבר מצוה and Shulchan Aruch Yoreh Deah 336:1 with Yad Avraham
