Based on the above, it is possible to explain the connection (and the sequence) of the subjects (discussed in the maamar) VeKibeil HaYehudim.1וְעַל פִּי זֶה יֵשׁ לְבָאֵר קֶשֶׁר (וְסֵדֶר) הָעִנְיָנִים (בְּהַמַּאֲמָר)
In the beginning of the maamar, the Rebbe Rayatz explains the interpretation of the verse, “And you shall command the Children of Israel,”בְּבֵאוּר הַפָּסוּק "וְאַתָּה תְּצַוֶּה" גוֹ', שֶׁבַּתְּחִלָּה מְבָאֵר אֶת הַפֵּרוּשׁ דִּ"וְאַתָּה תְּצַוֶּה אֶת בְּנֵי יִשְׂרָאֵל",
that Moshe connects and binds the Jewish people (to the Or Ein Sof, G‑d’s infinite light)שֶׁמֹּשֶׁה הוּא מְקַשֵּׁר וּמְחַבֵּר אֶת בְּנֵי יִשְׂרָאֵל (עִם אוֹר אֵין סוֹף)
through sustaining and nurturing their faith.עַל יְדֵי שֶׁהוּא זָן וּמְפַרְנֵס אֶת הָאֱמוּנָה,
Afterwards, he explains that in every generation, the shepherds of Israelוּלְאַחַר זֶה מְבָאֵר שֶׁגַּם רוֹעֵי יִשְׂרָאֵל שֶׁבְּכָל דּוֹר
(the “extensions of Moshe”)(אִתְפַּשְּׁטוּתָא דְּמֹשֶׁה)
strengthen the faith of the Jewish people.מְחַזְּקִים אֶת הָאֱמוּנָה דְּיִשְׂרָאֵל,
For example, Mordechai (the Moshe of his generation)וּכְמוֹ מָרְדְּכַי (מֹשֶׁה שֶׁבְּדוֹרוֹ)
reinforced the faith of the Jews to stand firm in the study of the Torah and the observance of the mitzvos.שֶׁחִזֵּק אֶת אֱמוּנָתָם שֶׁל יִשְׂרָאֵל לַעֲמֹד חָזָק בְּלִמּוּד הַתּוֹרָה וְקִיּוּם הַמִּצְווֹת,
Then, he explains the phrase “crushed for the luminary” –וּלְאַחַר זֶה מְבָאֵר הַפֵּרוּשׁ בְּכָתִית לַמָּאוֹר
that, as explained above, when the Jews are “crushed,” the “luminary,” the essential spark of G‑dliness within them, is revealed –
(which appears in the verse “And you shall command,” and as explained above, “you” apparently refers to Moshe himself).(שֶׁבַּפָּסוּק וְאַתָּה תְּצַוֶּה שֶׁמְּדַבֵּר לִכְאוֹרָה בְּמֹשֶׁה עַצְמוֹ),
For Moshe’s potential to reveal “the luminary” within every Jewכִּי זֶה שֶׁמֹּשֶׁה מְגַלֶּה בְּחִינַת הַמָּאוֹר דְּיִשְׂרָאֵל
(i.e., the essence of the soul)(עֶצֶם הַנְּשָׁמָה),
is expressed primarily by the extension of Moshe in the times of exileהוּא בְּעִקָּר עַל יְדֵי אִתְפַּשְּׁטוּתָא דִּילֵיהּ שֶׁבִּזְמַן הַגָּלוּת
For in Moshe’s era, there was no need for actual mesirus nefesh; the Jews were not presented with challenges that called for them to sacrifice their lives. And, as explained above, it is through actual mesirus nefesh that the essence of the Jews’ soul is revealed.
(when the Jews are “crushed”).(כָּתִית)
For these leaders arouse the power of mesirus nefesh within the Jewish people.שֶׁעוֹרְרוּ בְּיִשְׂרָאֵל כֹּחַ הַמְּסִירוּת נֶפֶשׁ שֶׁלָּהֶם,
Their mesirus nefesh represents the fundamental revelation of the essence of the soul, the level described as “the luminary.”שֶׁעַל יְדֵי זֶה הוּא עִיקַּר גִּלּוּי עֶצֶם הַנְּשָׁמָה, מָאוֹר.
To summarize: The maamar VeKibeil HaYehudim discusses the following three fundamental concepts:
a) that Moshe connects (tetzaveh) the Jewish people to G‑d by bringing the essence of their souls into revelation, alluded to by the phrase, “And you shall command the Children of Israel”;
b) that the “extensions of Moshe” perform the same function (there is no allusion to this concept in the opening verse); and
c) that the essential spark of G‑dliness within the Jewish soul is revealed through self-sacrifice in the era of exile, which is alluded to by the phrase “crushed for the luminary.”
One might have expected the maamar VeKibeil HaYehudim to have explained the first and the third concepts (for they are both alluded to in the verse) and then to explain the second concept. The second concept is introduced between the first two, however, because it is through the “extensions of Moshe” who bring the essence of the Jewish souls into revelation that the Jews are able to summon up the mesirus nefesh to confront the challenges of exile.
There is, however, a need for clarification:וְצָרִיךְ לְהָבִין,
According to the above explanation, the concept “crushed for the luminary” is related to the concept, “And you shall command the Children of Israel,”דִּלְפִי בֵּאוּר הַנִּזְכָּר לְעֵיל, הָעִנְיָן דְּ"כָתִית לַמָּאוֹר" שַׁיָּךְ לִ"וְאַתָּה תְּצַוֶּה אֶת בְּנֵי יִשְׂרָאֵל",
i.e., that Moshe, and the extension of Moshe in every generation,לָזֶה שֶׁמֹּשֶׁה וְאִתְפַּשְּׁטוּתָא דִּילֵיהּ שֶׁבְּכָל דּוֹר
connect and bind the Jewish people with the Or Ein Sof.מְקַשְּׁרִים וּמְחַבְּרִים אֶת יִשְׂרָאֵל עִם אוֹר אֵין סוֹף,
Until this point, the Rebbe has resolved several of the questions raised at the beginning of the maamar by explaining that Moshe serves as a “shepherd of faith.” The intent of that phrase is that he nurtures the faith of the Jewish people by bringing out the essential spark of G‑dliness that every Jew possesses. That essential spark of G‑dliness finds expression in mesirus nefesh, dedicating oneself to G‑d to the extent of self-sacrifice (“crushed for the luminary”). Moshe did not reveal this potential in the people of his generation because there was no necessity for it at that time. Instead, it was in the generations of exile that “the extensions of Moshe” brought this potential into expression.
Nevertheless, in the verse itself, the phrase “crushed for the luminary” comes after the phrase “and they shall bring you pure olive oil.”וּבְהַכָּתוּב נֶאֱמַר "כָּתִית לַמָּאוֹר" בְּהֶמְשֵׁךְ לִ"וְיִקְחוּ אֵלֶיךָ שֶׁמֶן זַיִת זָךְ",
This latter phrase (which relates how the Jews bring oil to Moshe)דְּעִנְיַן "וְיִקְחוּ אֵלֶיךָ" גוֹ' (שֶׁיִּשְׂרָאֵל מְבִיאִים שֶׁמֶן לְמֹשֶׁה)
alludes to the potential the Jews have to augment Moshe’s power, bringing him additional lightהוּא שֶׁיִּשְׂרָאֵל מוֹסִיפִים תּוֹסְפוֹת אוֹר בְּמֹשֶׁה
(as explained in sec. 2), using the example of the synergetic relationship between the head and the feet. What connection does this concept share with the concept of being “crushed for the luminary”?(כַּמּוּבָא לְעֵיל סְעִיף ב' מֵהַמַּאֲמָר).
To clarify that concept, in the following sections of the maamar, the Rebbe explains a second interpretation of the phrase “crushed for the luminary.” These explanations provide a different insight into how being “crushed” expresses “the luminary,” the essence of his soul. Through this insight, it is possible to understand the potential the Jews have to augment Moshe’s power.

Summary

It is thus possible to explain the conceptual sequence in the maamar VeKibeil HaYehudim. The maamar begins by stating that Moshe connects and binds the Jewish people to the Or Ein Sof through sustaining and nurturing their faith. Afterwards, it explains that the “extension of Moshe” in every generation strengthens the faith of the Jewish people and motivates them to mesirus nefesh. Moshe’s influence enables the expression of the motif of “crushed for the luminary,” that when the Jews are “crushed,” the “luminary,” the essential spark of G‑dliness within them, is revealed.
There is, however, a need for clarification: According to the above explanation, the concept of “crushed for the luminary” is related to the concept “And you shall command the Children of Israel,” i.e., that Moshe connects the Jewish people with the Or Ein Sof. Nevertheless, in the verse itself, the phrase “crushed for the luminary” comes after the phrase, “and they shall bring you pure olive oil.” As explained above, this latter phrase alludes to the potential the Jews have to augment Moshe’s power. This matter is explained in the later sections of the maamar.
