Efraim and Menashe
A question that is asked regarding the fatherly blessing to sons, is why not mention Avraham, Yitzchak, and Yakov, just as we mention Sara, Rivka, Rachel, and Leah, for our daughters. We ask Hashem to make our sons like Efraim and Menashe because they were the symbols of being G-d fearing Jews in the most adverse situation. When Yakov blesses Efraim and Menashe before his death, he asks Yosef, מי אלה? Who are these guys? This is strange because he had been living in Egypt for seventeen years. The Netivot Shalom says that the words, מי אלה, have all of the letters of Hashem’s name אל-הים. Yakov was astonished at how close his grandsons were to Hashem, even while growing up in the decadence of Egypt. This is the hope of every father for his son. No matter where he goes or chooses to live, he will never lose his closeness to Hashem, just like Efraim and Menashe.
