What did Eliezer mean when he asked Lavan and Besu'el to do "Chesed ve'Emes" with his master?
Seforno: By "Chesed" he meant that they would negate their own wish to marry Rivkah off to someone from their own country, and by "Emes', to do what was for the best advantage for their daughter - by marrying her off to the house of Avraham.
Ibn Ezra: When one undertakes to do - that is Chesed. When one carries out one's word - that is Emes. 1
Malbim: Emes is Hashem's decree. Chesed is that they will not negate it through their free choice, through demanding that Yitzchak come to see her first, and refusing to send her with Eliezer.
Ha'Emek Davar: It is Chesed of Emes, for it is clear that this is the Emes (correct thing to do).
Which is what "Chesed v'Emes" always means.
What did Eliezer mean when he said that he would turn to the right or to the left?
Malbim: I will take a daughter from Yishmael or from Kena'an,
Ha'Emek Davar: I will seek counsel.
The Oznayim la'Torah asks how Avraham could possibly have said such a thing, bearing in mind (a) his rejection of Lot
Rashi (8) writes that if she will not go, he may take a girl from Aner, Eshkol or Mamrei. Why did Eliezer change this?
Malbim (37): He was supporting his (false) claim that Avraham preferred a girl from his family.
