Genesis 27:39 - Wesley's Explanatory Notes

Esau likewise obtained a blessing: yet it was far short of Jacob's. In Jacob's blessing the dew of heaven is put first, as that which he most valued and desired: in Esau's the fatness of the earth is put first, for that was it which he had the principal regard to. Esau hath these, but Jacob hath them from God's hand. God give thee the dew of heaven, Genesis 27:28. It was enough to have the possession, but Jacob desired it by promise. Jacob shall have dominion over his brethren, for the Israelites often ruled over the Edomites. Esau shall have dominion, he shall gain some power, but shall never have dominion over his brother: we never find that the Jews were sold into the hands of the Edomites, or that they oppressed them. But the great difference is, that there is nothing in Esau's blessing that points at Christ, nothing that brings either him or his into the church, and without that the fatness of the earth, and the plunder of the field, will stand him in little stead. Thus Isaac by faith blessed them both, according as their lot should be.
