And [Lavan] said [to Eliezer]: “Come in, you blessed of G-d.” (24:31) The Midrash states: “Because he served that Tzaddik (Abraham) faithfully, he left the category of the cursed, and entered the category of the blessed.”⁴ 60:7. According to the Midrash, Abraham's servant, Eliezer, was a descendent of Canaan, of who it was said: “Cursed is Canaan, a servant of servants he will be to his brothers” (Genesis 9:25). The Baal Shem Tov said that even a non-Jew who eats something which contains a holy spark, and then serves a Jew with the vitality he gets from that food, elevates the spark to some degree, though not as much as if a Jew would eat it.
