1. Mose 25:27

Esau became "a cunning hunter, a man of the field," i.e., a man wandering about in the fields. He was his father's favourite, for "venison was in his mouth," i.e., he was fond of it. But Jacob was תּם אישׁ, "a pious man" (Luther); תּם, integer, denotes here a disposition that finds pleasure in the quiet life of home. אהלים ישׁב, not dwelling in tents, but sitting in the tents, in contrast with the wild hunter's life led by his brother; hence he was his mother's favourite.

The sacred historian, in this chapter, I. Takes his leave of Abraham, with an account, I. Of his children by another wife (Gen 25:1-4). 2. Of his last will and testament (Gen 25:5, Gen 25:6). 3. Of his age, death, and burial (Gen 25:7-10). II. He takes his leave of Ishmael, with a short account, 1. Of his children (Gen 25:12-16). 2. Of his age and death (Gen 25:17, Gen 25:18). III. He enters upon the history of Isaac. 1. His prosperity (Gen 25:11). 2. The conception and birth of his two sons, with the oracle of God concerning them (Gen 25:19-26). 3. Their different characters (Gen 25:27, Gen 25:28). 4. Esau's selling his birthright to Jacob (Gen 25:29-34).

25:27-34 Jacob and Esau each developed in accord with his initial characteristics (25:24-26). Esau, the reddish, hairy man, cared about physical things rather than spiritual things (see Heb 12:16); he was finally overcome by physical appetites and sold his birthright. Jacob, the heel grabber, knew the birthright’s value and drove a ruthless bargain to gain it presumptuously from his brother. 25:27 Esau was a skillful hunter and an outdoorsman—a wild man who loved wild country. Jacob had a quiet (or even) temperament and preferred to stay at home (literally dwelling in tents)—i.e., he was civilized.
