Genesis 32:3

The land of Seir; of which see Genesis 14:6, Genesis 36:9,20,21; whither Esau had removed his habitation from Canaan, partly out of discontent at his parents; partly as most convenient for his course of life; and principally by direction of Divine Providence, that Canaan might be left free and clear for Jacob and his posterity. The land of Seir, the country of Edom; so that Seir and Edom either are one and the same place; or rather Seir was a part of Edom. Some say both names are put here for distinction. For they make two lands of Edom, the one southward from Canaan, the other eastward, and this latter they understood here, alleging that the other, or southern, was so remote from Mount Gilead, whence Jacob was now descending, that Jacob need not fear Esau at that distance, nor send to him. But as that distinction seems to be without solid ground, so this reason seems to have but little weight in it, both because though this history immediately follows his descent from Mount Gilead, yet it might be done some competent time after it, and because Jacob in his journey to those parts where his father Isaac lived, and whither he was going, was still drawing nearer and nearer to Esau.
