There is a Medrash on our Parsha (that is brought down in RaShi in the Torah) that states; “Rabbi Achah said: ‘The ordinary conversation of the servants of the Patriarchs is more beloved before the Omnipresent than the Torah of their sons, for the section dealing with Eliezer is repeated in the Torah, whereas many fundamentals of the Torah were given only through allusions’”.
Our Rebbeim and leaders of ChaBaD have explained in Chassidic discourses (these can be found in the Alter Rebbe’s Maamor printed in the Tzemach Tzedek’s ‘Ohr HaTorah’ with the Tzemach Tzedek’s commentary, and they can also be found in the Mitteler Rebbe’s ‘Toras Chayim’ on our Parsha as well as in Maamorim thereafter) how many important aspects of Torah have been given in ‘hint’ form (as in the adage ‘A simple hint suffices for the wise’). Yet, the narrative of Eliezer is repeated in the Torah.
This is because the Parsha of Eliezer describes the ‘Shidduch’ between Yitzchok and Rivkah. (In other words, besides the general differences between the ‘Torah of the patriarch’s sons’ and the ‘ordinary conversation of the servants of the Patriarchs’ that are explained in Maamorim, the unique virtue of the narrative of Eliezer is also because it describes the Shidduch of Yitzchok and Rivkah.)
Because the union of Yitzchok and Rivkah alludes to the union of ‘Ze’eir Anpin’ and ‘Nukvah’, which is the basic Avodah of each and every one of B’nei Yisroel, the result of the performance of every single Mitzvah is also the union between ‘Ze’eir Anpin’ and ‘Nukvah’, and since ‘the actions of our Patriarchs are signs for the children’ as a result, this Parsha (which talks about the marriage of Yitzchok and Rivkah) is repeated in the Torah.
