The 12 Tribes and Yaacov's Blessing

12 Tribes

בראשית מח,ה : אֶפְרַיִּם וּמְנַשֶה כִּּרְ אוּבֵן וְשִּמְעוֹן יִּהְיוּ־לִּי

The Baal HaTurim observes that the phrase אפרים ומנשה have the same Gematria value (732) as the phrase ראובן ושמעון. That is why Yaacov said that they would receive an equal portion to them.

'And if you will ask', said Yaacov, 'how I can possibly place my grandchildren on a par with my children?” Yaacov says the answer is that when, “after I left Padan Aram, G-d said to me that I should be fruitful and multiply, that a nation and an assembly of nations will descend from me, I understood this to mean that I will still bear children from Rochel. But Rochel died. So now it is from you (Yosef) from whom these 'children' will descend!”
