Sforno on Genesis 35:12/ספורנו על בראשית ל״ה:י״ב

1ולזרעך אחריך אתן את הארץ, in due course, at the end of time, I will give your descendants the entire globe, not only the land of Israel. This was the real meaning of 28,14 “you will spread out to the west to the east and to the north and to the south.” This is also what Bileam prophesied when he said in Numbers 24,17 that Yaakov would uproot all the descendants of Seth, i.e. all of mankind.
