Verse 39. Esau likewise obtained a blessing: yet it was far short of Jacob's.
1. 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.
2. Esau hath these, but Jacob hath them from God's hand. God give thee the dew of heaven, ver. 28. It was enough to have the possession, but Jacob desired it by promise.
3. 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.
Verse 45. Why should I be deprived of you both? - Not only of the murdered, but of the murderer, who either by the magistrate, or by the immediate hand of God would be sacrificed to justice.
Verse 46. If Jacob take a wife of the daughters of Heth - As Esau has done. More artifice still. This was not the thing she was afraid of. But if we use guile once, we shall be very ready to use it again. It should be carefully observed, That altho' a blessing came on his posterity by Jacob's vile lying and dissimulation, yet it brought heavy affliction upon himself, and that for a long term of years. So severely did God punish him personally, for doing evil that good might come.
