וְאִם־לֹ֨א תֹאבֶ֤ה הָֽאִשָּׁה֙ לָלֶ֣כֶת אַחֲרֶ֔יךָ וְנִקִּ֕יתָ מִשְּׁבֻעָתִ֖י זֹ֑את רַ֣ק אֶת־בְּנִ֔י לֹ֥א תָשֵׁ֖ב שָֽׁמָּה׃
만일 여자가 너를 좇아 오고자 아니하면 나의 이 맹세가 너와 상관이 없나니 오직 내 아들을 데리고 그리로 가지 말지니라
Rashi
'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.
Chizkuni
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.
Da'at Zekenim
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.
