This parasha contains the second "Lekh Lekha" story - God once again commands Avraham to go forth on a mission. But is Rashi's comment on the first "Lekh Lekha" (in Chapter 12), that it means "go for your benefit and goodness" still relevant in Vayera? In Parashat Lekh Lekha, Avraham was commanded to go and sacrifice his past, leaving his birthplace for a new land. Here, Avraham is being commanded to go and sacrifice his future. Unlike Parashat Lekh Lekha, there are no promises here - just a commandment. As we explore this second "Lekh Lekha" and examine the parallels to the first "Lekh Lekha," we gain insight into Avraham's commitment.
