פּירוש אויף בראשית 24:8

'ונקית משבעתי וגו THEN SHALT THOU BE CLEAR FROM THIS MY OATH etc. — and take a wife for him from the daughters of Aner or Eshcol or Mamre.

רק את בני, “only my son etc.;” according to Rashi the restriction applied only to Avraham’s son Yitzchok, as he had been a offered as an Elevation Offering on G-d’s altar on the Holy Mountain of Moriah. It is therefore not appropriate for him to leave the Holy Land for any purpose.

ונקית משבועתי זאת, “you will be absolved from this oath I demand from you.” The apparently unnecessary word: “this,” is to warn Eliezer that the only part of the oath he will be absolved from if the woman refuses to leave her home, is Yitzchok must not go there to wed her. He would still be obligated to look for a suitable wife for Yitzchok. According to this interpretation, we must assume that the “friends” of Avraham, Aner, Eshkol, and Mamre, were not of Canaanitic descent.
