Vaishlach/I have kol vs rav

In parsha Vaishlach, Yaakov returns home after working for Laban for 20 years. Upon his entry into the Holy Land, he is faced by his brother Eisav accompanied by 400 men. Yaakov sends gifts to Eisav in order to mollify his (Eisav's) anger. When they finally meet, there is this curious verbal exchange between them:

וַיֹּ֕אמֶר מִ֥י לְךָ֛ כָּל־הַמַּחֲנֶ֥ה הַזֶּ֖ה אֲשֶׁ֣ר פָּגָ֑שְׁתִּי וַיֹּ֕אמֶר לִמְצֹא־חֵ֖ן בְּעֵינֵ֥י אֲדֹנִֽי׃

He [Eisav] said, What do you have to do with that whole camp that approached me? He [Yaakov] said, It was to find favor in the eyes of my master. (Gen 33:8)

וַיֹּ֥אמֶר עֵשָׂ֖ו יֶשׁ־לִ֣י רָ֑ב אָחִ֕י יְהִ֥י לְךָ֖ אֲשֶׁר־לָֽךְ׃

Eisav said, I have much. My brother, let what you have be yours (Gen 33:9)

 

The exact expression that Eisav used is יֶשׁ־לִ֣י רָ֑ב  "yesh li rav" - I have much. Eisav tries to persuade Yaakov to keep the gifts to himself. Upon hearing this, Yaakov does not give up, and responds:

קַח־נָ֤א אֶת־בִּרְכָתִי֙ אֲשֶׁ֣ר הֻבָ֣את לָ֔ךְ כִּֽי־חַנַּ֥נִי אֱלֹהִ֖ים וְכִ֣י יֶשׁ־לִי־כֹ֑ל

Please accept my blessing as it was brought to you, for God has been gracious to me, for I have all. (Gen 33:11)

 

The exact expression that Yaakov used is יֶשׁ־לִי־כֹ֑ל   "yesh li khol"  - I have all.

So Eisav uses "rav" while Yaakov uses "khol". What insight can we gain from this difference in expressions? We may further be perplexed by an interesting combination of both of these expressions in a single phrase in parsha Ki Tavo, where Moshe warns people of impending curses

וּבָ֨אוּ עָלֶ֜יךָ כׇּל־הַקְּלָל֣וֹת הָאֵ֗לֶּה וּרְדָפ֙וּךָ֙ וְהִשִּׂיג֔וּךָ עַ֖ד הִשָּׁמְדָ֑ךְ כִּי־לֹ֣א שָׁמַ֗עְתָּ בְּקוֹל֙ יְהֹוָ֣ה אֱלֹהֶ֔יךָ לִשְׁמֹ֛ר מִצְוֺתָ֥יו וְחֻקֹּתָ֖יו אֲשֶׁ֥ר צִוָּֽךְ׃

All these curses shall befall you; they shall pursue you and overtake you, until you are wiped out, because you did not heed your God יהוה and keep the commandments and laws that were enjoined upon you. (Deut. 28:45)

And why would these curses befall the people?

תַּ֗חַת אֲשֶׁ֤ר לֹא־עָבַ֙דְתָּ֙ אֶת־יְהֹוָ֣ה אֱלֹהֶ֔יךָ בְּשִׂמְחָ֖ה וּבְט֣וּב לֵבָ֑ב מֵרֹ֖ב כֹּֽל׃

Because you would not serve your God יהוה in joy and gladness over the abundance of everything,

(Deut 28:47)     

Because you did not serve Hashem with joy (simcha) from rav khol. Since rav is an aspect of Eisav, and khol is an aspect Yisroel (Yaakov), the verse seems to be saying that there will be suffering because we didn't serve Hashem with the joy of Eisav and Yisroel together, so to speak, in a single unified heart - לֵבָ֑ב (leivav). But how can Yisroel rejoice together with Eisav as a unified heart, if as we know, Eisav hates Yisroel? The answer is found in Psalm 149:2

יִשְׂמַ֣ח יִשְׂרָאֵ֣ל בְּעֹשָׂ֑יו בְּנֵֽי־צִ֝יּ֗וֹן יָגִ֥ילוּ בְמַלְכָּֽם׃

Let Israel rejoice in his maker; let the children of Zion exult in their king.(Psalm 149:2)

 

We will notice that "in his maker" is spelled   בְּעֹשָׂ֑יו which can be read as "with עֹשָׂ֑יו (Eisaiv)" where עֹשָׂ֑יו is the same as עֹשָׂ֑ו Eisav, but with an extra letter yud י inserted between 2nd and 3rd letters. In Torah, some individuals have an extra letter added to their names, in order to give them more holiness, or powers. For example, Joshua was added a yud at the beginning of his name to become Yehoshua יהושע, as it is said, (Numbers 13:16) “And Moses called Hoshea (הושע) the son of Nun, Yehoshua (יהושע)”. 

 

Similarly here, Eisav, apparently, will receive an extra yud  י which is the first letter of the name of Hashem יְהֹוָ֣ה as well as Yisroel יִשְׂרָאֵ֣ל , and with this addition, his nature will be transformed and to fulfill the prophecy יִשְׂמַ֣ח יִשְׂרָאֵ֣ל בְּעֹשָׂ֑יו - Yisroel and Eisav will rejoice מֵרֹ֖ב כֹּֽל from rav khol, as requested in (Deut 28:47).
