וישבתם לבטח בארצכם, “and you will live in your land feeling secure.” Previously, in 25,18, this has been worded slightly differently, when the Torah wrote: וישבתם על הארץ לבטח, “you will dwell on the land in security.” Here the Torah stresses the fact that G’d will consider the land as your land. However, during a famine, people will be exiled as it says: לא תוסף תת כחה לך. נע ונד תהיה בארץ, “the land will not continue to give you from its strength; you will be a nomad on earth wandering from place to place.” (Genesis 4,12) Or, as we find in Job 15,23: ?נודד הוא ללחם איה, “he wanders searching for bread, where is he?”

אשר פצתה את פיה לקחת את דמי אחיך, “because it opened its mouth, to accept, (hide) the blood of your brother, cooperating with you in hiding your foul deed.” As long as you and your descendants are living on earth; you will therefore have to find new earth to till, earth whose productivity has not been exhausted from the previous year’s harvest. [Kayin’s male descendants came to an end at the time of the deluge. If Noach’s wife was descended from Kayin, this does not contradict this interpretation, as women did not till the soil. Ed.] We have a verse in Job 15,23, which describes the wicked man as wandering in search of bread without succeeding.”
