INTRODUCTION
Parshat Korach opens with a pasuk that seems to be grammatically incorrect: "Va'yikach Korach..." - And Korach, the son of Yizhar, the son of Khat, the son of Levi, TOOK, and Datan and Aviram [the sons of Eliav] and Oan [the son of Pelet] the sons of Reuven." (16:1)

This opening sentence simply states that Korach TOOK, without explaining WHAT he took! In fact, this pasuk is so ambiguous that almost every commentator offers a different interpretation. For example:
Rashi - Korach took himself to a 'different side';
Ramban - he took an "eytzah" (counsel) into his heart;
Ibn Ezra & Chizkuni - he took 'other people';
Sforno - he took the 250 'national leaders'.
[Note as well how just about every translation of this pasuk attempts to 'improvise' in some manner or other.]

However, no matter which interpretation is most accurate, a more basic question remains, i.e.: Why does the Torah begin this parsha in such an ambiguous manner? After all, one would assume that the Torah's message would have been clearer had this pasuk been written 'properly'!

In the following shiur, we will show how the answer may lie in the distinct style that the Torah uses to describe this incident. [In other words, we claim that the Torah deliberately writes in this style - in order to deliver its message!] To uncover this special style, we must undertake a careful reading of Parshat Korach (i.e. Bamidbar chapter 16), while paying attention to the nature of the various 'complaints' that are raised.

FIGHTING FOR A COMMON CAUSE
From a cursory reading of Parshat Korach it seems that Korach, Datan & Aviram, and the 250 men all unite behind a common cause. Their joint criticism of the leadership of Moshe and Aharon, voiced in their opening protest, demonstrates this united opposition:

"...and they gathered against MOSHE AND AHARON saying: You have taken too much - for the ENTIRE COMMUNITY IS HOLY and God is in their midst, why then do you RAISE YOURSELVES ABOVE God's congregation?" (16:3)

In response to this opening complaint, Moshe offers a 'test' - that seems to serve a some type of 'showdown' (see 16:4-7). Let's examine the details of this 'test', for it should provide us at least with a hint concerning what they are truly complaining about: "Come morning, and God will make known who is His and who is holy... and he whom He has chosen...
This you shall do, take fire-pans, Korach and his entire group, ... and put on them KTORET before God [i.e. at the Mishkan]... and he [who's offering] God shall choose will be established as "kadosh"... (see 16:5-7)

As you review these psukim, note how it remains rather unclear concerning the precise purpose of this 'ktoret test' as well! Will it determine who should be the true LEADER? If so, this would imply that only ONE offering will be accepted. However, if that was the case, Moshe as well as Aharon should participate! Furthermore, if this is simply a 'showdown' between Moshe and Korach, why should the 250 men participate as well?

More likely, the purpose of this 'test' is to determine who is permitted to OFFER KORBANOT (i.e. their complaint is for 'spiritual equality'). If so, this would imply that possibly ALL of the offerings may be accepted (or at least some of them). This would explain why all the 250 men and Aharon participate (and why Moshe doesn't).

SPIRITUAL EQUALITY

To support this latter understanding, we simply need to take a look at Moshe's second response to Korach (see 16:8-11), i.e. in his additional censure of the bnei Levi" involved:

"Hear me, sons of Levi - is it not enough that God has designated you to come close [i.e. to assemble and carry the Mishkan]... and now you and your fellow Levites DO YOU SEEK THE KEHUNA [priesthood] as well.... - why then do you complain AGAINST AHARON." (see 16:8-11)

Apparently, these dissidents believe that the limitation of offering korbanot to Aharon's family stems from Moshe's nepotism, rather than from a divine command. [See Chizkuni 16:15.] Hence, this 'ktoret test', as Moshe suggests, will determine who indeed is capable of offering korbanot - i.e. only Aharon, or possibly all (or at least some) of the 250 men as well. [See also 16:16-17.]

ENTER - GROUP TWO

Up until this point, we are left with the impression that everyone mentioned in the opening two psukim - i.e. Korach, Datan, Aviram, and the 250 men - join together in this protest. Hence, we should expect all of them to participate in this 'showdown'. However, as the narrative continues, a very different picture emerges. Note from 16:12 that Datan & Aviram, for some reason, are singled out:

"And Moshe sent for DATAN & AVIRAM, but they answered: WE WILL NOT COME UP..." (see 16:12-14)

"Is it not enough that you took us out of a land flowing with milk and honey [referring to Egypt!] to die in the desert and NOW - YOU CONTINUE TO ACT AS LORD OVER US! You have not even brought us to a land flowing with milk & honey (as Moshe had promised)... [therefore] we will not come up!" (16:13-14)

Clearly, this complaint differs drastically from Korach's initial objection to the KEHUNA! Korach and the 250 men challenge Aharon's exclusive status, but never question Moshe's leadership. After all, they all agree to the 'test' that Moshe himself initiates. Datan and Aviram, however, challenge specifically Moshe's leadership.

MOSHE'S PRAYER
Conclusive proof of this distinction can be found in Moshe's immediate reaction to Datan & Aviram's complaint. Pay careful attention to how Moshe turns to God in prayer:

"And Moshe became angry and said to God - 'al teyfen el MINCHATAM' - Pay no attention to their 'oblation' - I did not take from them a single donkey, nor have I wronged anyone of them." (see 16:15)

[Note how the commentators dealt with this problem. Even though the first opinion of Rashi claims that "minchatam" indeed refers to the KTORET offering, Ramban (rightly so) disagrees - suggesting that it refers to any type of prayer (or offering) that they may offer. See also Ibn Ezra & Seforno who explain this pasuk in a similar manner.]

Furthermore, the reason that Moshe advances - "for I have not taken anything from them" - clearly relates to Moshe's counter-claim that his leadership has been without corruption. Therefore, this entire prayer relates to Datan & Aviram's complaint against his leadership. Moshe simply turns to God to affirm the legitimacy of his own [divinely appointed] leadership that has now been challenged. Moshe reminds God that he has been a faithful leader who never abused his power.

TWO GROUPS - TWO GRIPES
Let's summarize what has emerged thus far. We have identified TWO independent grievances, raised by TWO independent groups, situated in TWO different locations:

GROUP ONE - the 250 men ["adat Korach"]- protest Aharon's exclusive rights to the KEHUNA. They stand ready for their 'test' at the OHEL MOED;
[Note that the Torah consistently refers to this group as "adat Korach" (see 16:5,6,11).]

GROUP TWO - Datan & Aviram (& followers) - complain against the POLITICAL leadership of MOSHE. They gather in the territory of shevet Reuven.
[This location is later referred to as "Mishkan Korach Datan v'Aviram" (see 16:24-27).]

Of course, it remains to be seen where Korach himself stands on these two issues, but there can be no doubt that there are two groups with two very different agendas.

RE-ENTER GROUP ONE Up until this point (i.e. 16:1-15), the narrative, although a bit complex, has flowed in a logical order: it first presents both groups, followed the presentation of the individual complaints of each faction. But now, for some reason, the narrative begins to 'see-saw,' seemingly randomly, between Moshe's confrontations with each of these two groups.
Note how in 16:16 the narrative abruptly switches from Moshe's response to Datan & Aviram (group II) back to his original confrontation with "adat Korach" (group I):

"And Moshe said to Korach, tomorrow, you and all your company [the 250 men] be before God [at the Mishkan], you and they and Aharon..."

Then the narrative continues to describe this confrontation: The next morning, all 250 men assemble at the Ohel Moed ready with their "machtot" (fire-pans) and "ktoret" (16:18), while Korach rallies a mass crowd to watch (16:19). But then, just as we await the 'showdown', again we find an abrupt change in the narrative.

RE-ENTER GROUP TWO

At this point we find a new 'parshia' (16:20-22), which includes (for the first time) God's direct intervention. As you study these psukim, note how it is not quite clear who "ish echad" and "ha'EYDAH" refer to:

"And God spoke to Moshe & Aharon: 'Separate yourselves from among this congregation, that I may consume them in a moment.' And they fell upon their faces, and said: 'O God, the God of the spirits of all flesh, shall - "ish echad" - one man sin, and You will be wroth with - "kol ha'EYDAH" -the entire congregation?' (16:20-22)

To answer this question, let's see how God answers this prayer:

"And God told Moshe, speak to the EYDAH and warn them - WITHDRAW yourselves from the area of MISHKAN KORACH DATAN V'AVIRAM." (16:23-24)

With this in mind, let's attempt to identify whom "eydah" refers to in God's reply to Moshe's prayer (in 16:24). To save the "eydah" from this "ish echad", Moshe must instruct the "eydah" to evacuate the area surrounding Mishkan Korach Datan & Aviram. Hence, the "eydah" must refer to a group of people who have gathered around Mishkan Korach Datan v'Aviram in the Tribe of Reuven. However, this conclusion is rather baffling, for only five psukim earlier, the word "eydah" was used to describe a group of people who had gathered around the OHEL MOED to watch the "ktoret" showdown (see 16:19)! Once again, we find how the narrative has 'jumped' from Group One [the 250 men offering ktoret] to Group Two [Datan & Aviram].

To prove that there are indeed two groups involved, simply note what takes place in the next pasuk, as Moshe fulfills God's command.
Recall that Moshe must issue a warning to the EYDAH that has gathered around the campsite of Datan & Aviram. As this "eydah" refers to Group Two, Moshe must now LEAVE the area of the OHEL MOED (where Group One has assembled) and GO to the area where Group Two is located - i.e Mishkan Korach, Datan & Aviram:

"And Moshe GOT UP and WENT TO Datan & Aviram... and he said to the people: MOVE AWAY from the tents of these wicked people... lest you be wiped out for all their sins..." (16:25-26)

Because Group Two challenges Moshe's leadership (and not Aharon's priesthood), it must be Moshe himself (and NOT Aharon) who confronts this group. Note that Aharon does not accompany Moshe (in 16:25). Instead, he remains at the Ohel Moed, prepared for the showdown with the 250 men (Group One), i.e. the group that questions his KEHUNA.

TWO GROUPS - TWO PUNISHMENTS
At this point, God must prove to the political dissidents that it was indeed His choice that Moshe be appointed leader. Therefore, God Himself must 'create' a "beriya" - a new form of creation - to punish this group. Those who distance themselves from this group are saved (see 16:27-34). However, note that the ground miraculously devours only the members of Group Two - i.e. Datan & Aviram and their staunchest followers.

But what happened in the meantime to "adat Korach" (Group One), i.e. the 250 men. Note that the last time they were mentioned was back in 16:17-19, as they prepared to the "ktoret" showdown; but we were never told what happened to them! For some reason, the Torah leaves us in suspense about their fate; until the very last pasuk of this narrative (and in a very incidental manner):

"And a fire came forth from God and consumed the 250 men who were offering the ktoret." (16:35)

GROUP ONE -
the 250 men at the Ohel Moed - CONSUMED BY FIRE.
GROUP TWO -
Datan & Aviram & Co. - SWALLOWED BY THE GROUND.

So where is Korach in all of this? Was he consumed by fire in the Mishkan together with Group One; or swallowed up by the ground - together with Group Two?
He couldn't be two places at the same time, could he?

KORACH - THE POLITICIAN

To appreciate the nature of Korach's involvement, we must understand his connection to each of these two groups. Before we begin, let's use a table to summarize our analysis thus far:

GROUP ONE	GROUP TWO
Members: 250 men	Datan & Aviram + followers
Claim : priesthood	new political leadership
Against: Aharon	Moshe
Reason: spiritual equality	failure of leadership
Location: Ohel Moed	shevet Reuven
Punishment: consumed by fire	swallowed by the ground

At first glance, it appears that each group has some basis for a legitimate complaint.
By challenging the restriction of the KEHUNA to the family of Aharon, Group One assert their right, as well as the right of others, to offer korbanot.

By challenging the political leadership of Moshe, Group Two voices their concern for the welfare and future of Am Yisrael. In their opinion, remaining in the desert is equivalent to national suicide (see 16:13).
Although Group One has little in common with Group Two, the Torah presents this story as if only one group exists. The narrative accomplishes this by 'jumping back and forth' from one group to the other. The following chart (of perek 16) illustrates this 'textual zig-zag':

PASUK	GROUP	TOPIC
1- 4	both	Introduction
5-11	ONE	Complaint of those who want 'kehuna'
12-15	TWO	Summons of Datan & Aviram & their refusal
16-19	ONE	The test of the "ktoret"
20-22	both?	Moshe's tfila that God punish only the guilty
23-34	TWO	earth swallows Datan & Aviram & followers
25	ONE	fire consumes the 250 men

Why does the Torah employ this unusual style? How does it help us better understand Korach's involvement with each group?

KORACH - WHERE ARE YOU?

First, we must ascertain to which group Korach belongs.
Clearly, he leads Group One, which demands the "kehuna" (see 16:6-8,16-19). Yet, at the same time, he is so involved with Group Two that his name appears first on the banner in front of their party headquarters - "Mishkan KORACH Datan v'Aviram"!
Furthermore, although Korach himself is never mentioned in the punishment of Group Two (scan 16:23-34 carefully to verify this), many of his followers, described by Chumash as "ha'adam asher l'Korach", are swallowed up by the ground (see 16:32) together with Datan & Aviram.
In fact, it remains unclear precisely how Korach himself dies. Was he swallowed by the ground or consumed by the fire? The 'last time he was spotted' was in 16:19 together with the 250 men (Group One) at the Ohel Moed. But from 16:25 it seems that only the 250 men were consumed, but NOT Korach himself! On the other hand, 16:32 informs us that Datan & Aviram and ALL of Korach's men were swallowed up - but Korach himself seems to be 'missing'! Did he escape at the last minute from both?
Apparently not, for later in Sefer Bamidbar (see 26:9-10) we are told quite explicitly that Korach was indeed swallowed. But to complicate matters even further, Devarim 11:6 implies that only Datan & Aviram were swallowed up.
[Based on the complexity of these psukim, the Gemara in Sanhedrin 110a suggests that he received both punishments! First he was burnt by the fire at the Ohel Moed, and then his bodied rolled to the area of Datan v'Aviram and swallowed up by the ground. ] (See also Ibn Ezra on 16:35.)

So why does the Torah describe these events in such a complex manner? What can this manner of presentation teach us about the nature of Korach's involvement? Finally, why does Chumash attempt to give us the impression that Korach may be in two places at the same time?
One could suggest that this 'zig-zag' style reflects the nature of the coalition that exists between these two dissident groups, for they share only one common denominator- KORACH.
But what was Korach's motivation in all of this? 
To answer this question, let's return to the opening pasuk of this Parsha (see introduction). By not telling us what Korach 'took', the Torah wants the reader to ask this very question - what did Korach take?
[If you don't ask yourself this question as you begin reading, you may never notice the existence of these two groups as you continue.]

COALITION POLITICS

Korach 'took' two ostensibly 'legitimate' protest groups and joined them together to form his own political power base. [See Ramban 16:1.] Whereas each group alone may have not dared to openly challenge Moshe and Aharon, Korach encourages them to take action. Datan and Aviram, 'inspired' by Korach, establish their own 'headquarters' - "Mishkan Korach, Datan, & Aviram" - in defiance of Moshe's leadership. Likewise, the 250 men, including members of shevet Levi, are roused to openly challenge the restriction of the KEHUNA to Aharon.
Rather than encouraging open dialogue, Korach incites these two factions to take forceful action. Korach probably saw himself as the most suitable candidate to become the next national leader. To that end, he involves himself with each dissenting group. [Anyone familiar with political science (i.e. current events and/or world history) can easily relate to this phenomenon.] Korach is simply what we would call a 'polished politician'. His true intention is to usurp political power. Towards that goal, he takes advantage of private interest groups.

A LESSON FOR ALL GENERATIONS The Mishna in Pirkei Avot (5:17) considers the rebellion of Korach as the paradigm of a dispute that was "sh'lo l'shem sha'mayim" (an argument not for the sake of Heaven).
Why is specifically Korach chosen for this paradigm? After all, the arguments presented by Korach ("for the entire nation is holy", etc.) seem to imply exactly the opposite - that it was actually an argument "l'shem shamayim" (for the sake of Heaven). Pirkei Avot may be teaching us the very same message that the Torah may allude to through its complex presentation of these events. Precisely because Korach and his followers claim to be fighting "l'shem shamayim," Chazal must inform us of Korach's true intentions. Korach may claim to be fighting a battle "l'shem shamayim," but his claim is far from the truth. His primary interest is to promote himself, to build a power base from which he himself can emerge as the new leader. Parshat Korach thus teaches us that whenever a dispute arises over community leadership or religious reform, before reaching conclusions we must carefully examine not only the claims, but also the true motivations behind the individuals who promote them. On a personal level, as well, every individual must constantly examine the true motivations behind all his spiritual endeavors.
