Zitat Kommentar zu Schemuel I 12:6

ואת הנפש אשר עשו בחרן, the male and female servants they had acquired in Charan. The word עשו must be understood as similar to Deuteronomy 8,17 עשה לי את כל החיל הזה, “has gotten me this wealth.” According to Onkelos, the word עשו refers to the people whom Avram and Lot had succeeded in bringing back to monotheism, i.e. the same religion as that professed by Avram. Lot too, professed the belief in the one and only invisible G’d, the Creator of the universe Lot did not merely join Avram because he was his uncle and much younger than his grandfather, but he shared his religious beliefs and was active as an evangelist for that faith himself. This is the reason why the Torah wrote the word עשו in the plural mode instead of the singular. According to our sages (Bereshit Rabbah 39,14) the plural mode of the word עשו is meant to prove that both Avram and Sarai, each were active in converting their respective friends to monotheism. The use of the root עשה to describe such “brainwashing,” is also found in Samuel I 12,6 אשר עשה משה את משה ואת אהרן, where it refers to G’d having been the mentor of both Moses and Aaron.
