What do we learn from "l'Sa'avah Yevakesh Nifrad"?
Rashi citing Nazir 23b: This refers to Lot. He separated from Avraham for the desires of his heart 1 .
Rashi: One who separates from Hashem, not to guard His Mitzvos, due to his heart's desires, he pursues his Yetzer ha'Ra.
R. Yonah #1: The verse scorns one who is drawn after desire. He is separated from every friend 2 , for one cannot bear a friend who is drawn after his desire, and never nullifies his desire due to his friend's desire. The prefix Lamed is extra, like "Hargu l'Avner" (Shmuel II, 3:30).
