Genesis 35:22 And it came to pass, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father's concubine: and Israel heard it.
[Patriarchs & Prophets pp 206>207] On the way to Ephrath another dark crime stained the family of Jacob, causing Reuben, the first-born son, to be denied the privileges and honors of the birthright. At last Jacob came to his journey's end, “unto Isaac his father unto Mamre, ... which is Hebron, where Abraham and Isaac sojourned.” Here he remained during the closing years of his father's life. To Isaac, infirm and blind, the kind attentions of this long-absent son were a comfort during years of loneliness and bereavement. Jacob and Esau met at the deathbed of their father. Once the elder brother had looked forward to this event as an opportunity for revenge, but his feelings had since greatly changed.
And Jacob, well content with the spiritual blessings of the birthright, resigned to the elder brother the inheritance of their father's wealth—the only inheritance that Esau sought or valued. They were no longer estranged by jealousy or hatred, yet they parted, Esau removing to Mount Seir. God, who is rich in blessing, had granted to Jacob worldly wealth, in addition to the higher good that he had sought. The possessions of the two brothers “were more than that they might dwell together; and the land wherein they were strangers could not bear them because of their cattle.” This separation was in accordance with the divine purpose concerning Jacob. Since the brothers differed so greatly in regard to religious faith, it was better for them to dwell apart.
Esau and Jacob had alike been instructed in the knowledge of God, and both were free to walk in His commandments and to receive His favor; but they had not both chosen to do this. The two brothers had walked in different ways, and their paths would continue to diverge more and more widely. There was no arbitrary choice on the part of God by which Esau was shut out from the blessings of salvation. The gifts of His grace through Christ are free to all. There is no election but one's own by which any may perish. God has set forth in His word the conditions upon which every soul will be elected to eternal life—obedience to His commandments, through faith in Christ.
Deuteronomy 11:26 Behold, I set before you this day a blessing and a curse; 27 A blessing, if ye obey the commandments of the Lord your God, which I command you this day: 28 And a curse, if ye will not obey the commandments of the Lord your God, but turn aside out of the way which I command you this day, to go after other gods, which ye have not known.
May The Lord add His blessing to the study of His word. God bless!
