Commento su Genesi 13:5

ההלך את אברם WHO WENT WITH ABRAM — What brought it about that he possessed all this? The fact that he was accompanying Abram (Genesis Rabbah 41:3; Pesikta Rabbati, שמיני).

וגם ללוט, the word וגם is meant to add that even Lot, who had only been a member of Avram’s entourage, was showered with wealth while Avram stayed in Egypt. [clearly a very short time if G’d punished Pharaoh already on the same night that he had taken Sarai. Ed.]

What brought this about? Rashi is answering the question: It is already written (v. 1), “Avram went ... together with Lot into the south,” [so why is it repeated?]
