He does not, indeed, commend Jacob on account of those rare and excellent qualities, which are especially worthy of praise and of remembrance, but only says that he was simple. The word תם ( tam,) although generally taken for upright and sincere, is here put antithetically. After the sacred writer has stated that Esau was robust, and addicted to hunting, he places on the opposite side the mild disposition of Jacob, who loved the quiet of home so much, that he might seem to be indolent; just as the Greeks call those persons οἰκόσιτους oikositous, who, dwelling at home, give no evidence of their industry. In short, the comparison implies that Moses praises Esau on account of his vigor, but speaks of Jacob as being addicted to domestic leisure; and that he describes the disposition of the former as giving promise that he would be a courageous man, while the disposition of the latter had nothing worthy of commendation. Seeing that, by a decree of heaven, the honor of primogeniture would be transferred to Jacob, why did God suffer him to lie down in his tent, and to slumber among ashes; unless it be, that he sometimes intends his election to be concealed for a time, lest men should attribute something to their own preparatory acts?
