Musar sobre Génesis 24:50

Another indication that one must strive to lead a morally upright life is found in the statement of Shabbat 152a which describes Torah scholars as becoming wiser as they get older, whereas secularly oriented people become progressively more senile in their old age. This statement also utilizes the wording in our פרשה, as it associates Sarah's last seven years with the word "years" in the plural, i.e. years filled with additional meaning.

Bereshit Rabbah 60,13 points out that as a result of Laban's blessing in Genesis 24,60: אחותנו את היי לאלפי רבבות, "Our sister! May you grow into thousands and tens of thousands," "thousands" i.e. אלו תימן, אלוף קנז, are descended from her through Esau, and "tens of thousands" i.e. רבבה כצמח השדה נתתיך, through Jacob as per Ezekiel 16,7. Laban eventually conceded the validity of these blessings. Even the part which was negative, i.e. the blessings for Esau, Laban "purified," i.e. he agreed for Esau to embrace true monotheism. This is evident from Laban's words in Genesis 24,50 "This matter was decreed by G–d; we cannot speak to you either bad or good." Laban acknowledges that everything is in the hands of G–d, and he says "here is Rebeccah, take her and go."

This is why he immediately brought Eliezer and his entourage to his home, prepared fodder, etc. He did not do this out of charitable considerations. This is also the reason he preempted his father and asserted that since the match was made in Heaven, they could certainly not object. He was afraid that his father would come up with some scheme to delay this match. He was anxious to earn the fee that Eliezer had promised him. As soon as Eliezer had heard Laban say "here is Rebeccah, take her and be on your way," Eliezer thought that the matter had been finalised; he thanked G–d and brought out all kinds of golden and silver trinkets as well as costly garments, as described in 24,52. He gave all to Rebeccah, whereas he gave Laban and his family only exotic fruit and other delicacies.
