Musar for Genesis 13:1

Abraham planted an אשל, (another word for orchard); he entered and emerged spiritually whole. Abraham traversed the whole land of Canaan (Genesis 12,6) descended into the land of Egypt, a country filled with all sorts of impurities. He was saved from being affected by any of them, and the Torah reports him as having ascended again from Egypt "southward" (Genesis 13,1). [The term "southward" is geographically incorrect as the land of Canaan is situated north of Egypt. Ed.] All of Abraham's ascents were "southward," in line with the statement of our sages that he who wishes to acquire true wisdom should turn "southward." (Baba Batra 25b). Rabbi Akiva, too, entered the orchard spiritually whole and emerged whole.
