Génesis 24:12 Comentario: Kli Yakar, Or HaChaim, Radak & Rav Hirsch

“Please make happen [hakreh] before me today.” Some say that he [Eliezer] was asking God to arrange for him [to meet] an important young woman who normally never goes out at all, and that just for this moment she should happen [bemikreh] to come out now, specifically before him, so that she would not be among the women who frequently go out [implying immodesty]. This is why the Torah states no man had known her, meaning that no one recognized her because she had never gone out except for this one time. This is why he needed to ask her whose daughter are you?, and why didn’t he ask the other young women who were there — for undoubtedly she didn’t go alone — but rather [he asked her] because no man had known her, meaning no one recognized her.

ויאמר: ה׳ הקרה נא, He said: "G'd! please make it happen, etc." Eliezer was certain that his master's prayer that G'd would send His angel ahead of Eliezer to facilitate his mission would be fulfilled. He added a prayer expressing the hope that he would be found worthy to be the instrument through which Abraham's prayer would be fulfilled. It happens on occasion that the prayer of the original petitioner goes unanswered due to the unworthiness of the petitioner's messenger.

ויאמר...הקרה נא לפני, “arrange for me,” as had been predicted by Avraham. This is what he meant when he added ועשית חסד עם אדני אברהם, “perform an act of loving kindness for my master Avraham.”
