1950 Years Part 3

Part 1
Part 2

In part 2, we explained how the שם הויה (i.e. 26) generations multiplied by 75 years per generation equals the 1950 years since the Hurban.

This idea can also be brought out from the beginning of the Parasha we just read:

ג  וָאֵרָא, אֶל-אַבְרָהָם אֶל-יִצְחָק וְאֶל-יַעֲקֹב--בְּאֵל שַׁדָּי; וּשְׁמִי יְהוָה, לֹא נוֹדַעְתִּי לָהֶם.

3 and I appeared unto Abraham, unto Isaac, and unto Jacob, as God Almighty, but by My name YHWH I made Me not known to them.

The Midrash Tanhuma on Vayeitzei tells about the rungs of Yaakov's ladder: the angel of Bavel went up 70 rungs corresponding to the 70 years of Galut Bavel - and he descended, the angel of Madai went up 52 rungs corresponding to the 52 years of Galut Madai - and he descended, and the angel of Yavan went up 180 rungs corresponding to the 180 years of Galut Yavan - and he descended.

This Midrash tells us the total amount of years of the first 3 exiles: 70 + 52 + 180 = 302 years.

The Zohar Hadash p. 8 column 4 says that we were redeemed from the first 3 exiles in the merit of Avraham, Yitzhak, and Yaakov, while we will be redeemed from the 4th exile in the merit of Moshe Rabbeinu.

Therefore, the verse in Va'era is telling us that Hashem appeared to Avraham, Yitzhak, and Yaakov ב-א-ל ש-ד-י - which has the Rashei Teivot ב"ש, which is gematria 302 - the number of years of the first 3 exiles.  The remaining letters (א-ל-ד-י) have the gematria of 45, the same as גאולה, showing that the Geula of those exiles was in the merit of the Avot.

The next part of the verse is telling us saying that Hashem's name of הויה was not made known להם.  In other words, the fact that the gematria of the name of הויה (i.e. 26) is to be multiplied by the gematria of להם (i.e. 75) was not made known to anyone.

Postscript:

An interesting Remez to the fact that the word להם hints to the future is from the very next verse, upon which the gemara Sanhedrin 90b (Daf | Text | English) expounds:

תניא רבי סימאי אומר מניין לתחיית המתים מן התורה שנאמר (שמות ו) וגם הקימותי את בריתי אתם לתת להם את ארץ כנען לכם לא נאמר אלא להם מכאן לתחיית המתים מן התורה

It has been taught: R. Simai said: Whence do we learn resurrection from the Torah? — From the verse, And I also have established my covenant with them, [sc. the Patriarchs] to give them the land of Canaan:¹⁴  '[to give] you' is not said, but 'to give them' [personally]; thus resurrection is proved from the Torah.¹⁵

Thus, perhaps, the Torah was hinting to us that להם is the key to the calculation of the end of our exile.

May we merit to quickly see the end of the Edomite Exile and the beginning of our Final Redemption.
