וַיֹּ֤אמֶר אֵלָיו֙ הָעֶ֔בֶד אוּלַי֙ לֹא־תֹאבֶ֣ה הָֽאִשָּׁ֔ה לָלֶ֥כֶת אַחֲרַ֖י אֶל־הָאָ֣רֶץ הַזֹּ֑את הֶֽהָשֵׁ֤ב אָשִׁיב֙ אֶת־בִּנְךָ֔ אֶל־הָאָ֖רֶץ אֲשֶׁר־יָצָ֥אתָ מִשָּֽׁם׃
И сказал ему слуга: 'В конце концов, женщина не захочет следовать за мной на эту землю; должен ли я вернуть сына твоего в землю, откуда ты пришел?'
Chizkuni
ההשיב אשיב את בנך, “shall I really take back your son there? This is a peculiar question by Eliezer, as Yitzchok had never been out of the land of Canaan. Seeing that Eliezer had been sent back there on behalf of Yitzchok, his question was perfectly in order. We find a similar verse in Ruth 1,22 where Naomi is described as “returning” to the land of Israel with her daughterinlaw , although the daughter inlaw, Ruth, had never set foot in that land.
Ramban
PERADVENTURE THE WOMAN WILL NOT BE WILLING. The meaning [of the definite article in the word ha’ishah] is that it refers to “the woman to whom I will speak of all the women there”, or it may mean the woman who is fit for Isaac.
Rashbam
?ההשב אשיב את בנך, to the land of your ancestors? He meant that even though he might not find there any members of Avraham’s former family. He still referred to this as a השבה “a return.”
