Unlike his twin brother, Jacob seems to have been free from any physical peculiarities; his smoothness (
Ge 27:11) is only predicated of him in contrast to Esau's hairiness. These brothers, as they developed, grew apart in tastes and habits. Jacob, like his father in his quiet manner of life and (for that reason perhaps) the companion and favorite of his mother, found early the opportunity to obtain Esau's sworn renunciation of his right of primogeniture, by taking advantage of his habits, his impulsiveness and his fundamental indifference to the higher things of the family, the things of the future (
Ge 25:32). It was not until long afterward that the companion scene to this first "supplanting" (
Ge 27:36) was enacted. Both sons meanwhile are to be thought of simply as members of Isaac's following, during all the period of his successive sojourns in Gerar, the Valley of Gerar and Beersheba (
Ge 26). Within this period, when the brothers were 40 years of age, occurred Esau's marriage with two Hittite women. Jacob, remembering his own mother's origin, bided his time to find the woman who should be the mother of his children. The question whether she should be brought to him, as Rebekah was to Isaac, or he should go to find her, was settled at last by a family feud that only his absence could heal. This feud was occasioned by the fraud that Jacob at Rebekah's behest practiced upon his father and brother, when these two were minded to nullify the clearly revealed purpose of the oracle (
Ge 25:23) and the sanctions of a solemn oath (
Ge 25:33). Isaac's partiality for Esau arose perhaps as much from Esau's resemblance to the active, impulsive nature of his mother, as from the sensual gratification afforded Isaac by the savory dishes his son's hunting supplied. At any rate, this partiality defeated itself because it overreached itself. The wife, who had learned to be eyes and ears for a husband's failing senses, detected the secret scheme, counterplotted with as much skill as unscrupulousness, and while she obtained the paternal blessing for her favorite son, fell nevertheless under the painful necessity of choosing between losing him through his brother's revenge or losing him by absence from home. She chose, of course, the latter alternative, and herself brought about Jacob's departure, by pleading to Isaac the necessity for obtaining a woman as Jacob's wife of a sort different from the Canaanitish women that Esau had married. Thus ends the first portion of Jacob's life.
