The physics of the family tree: the deeper the roots, the sweeter the fruit.
Twins are born to Rebecca and Isaac. These were not identical twins. One was destined to become a man of the fields, while the other would grow to be a man of the academic tents. One would give birth to the Western world, while the other would give birth to the Nation of Israel. Esau and Jacob, two brothers with very different storylines. The arms are the arms of a warrior, but the voice is the voice of a scholar. After tricking his brother out of the rites of the firstborn, by utilizing the arms of a warrior but the voice a scholar, Jacob flees from the wrath of his twin.
