“(For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;)”
King James Version (KJV)
Ro 9:11 For [the children]. The children, yet unborn, were both Isaac's seed according to the flesh; hence, according to the flesh, of the promised seed, and both equally without works, "neither having done good nor evil". That the purpose of God according to election might stand. That it might stand forth that he made the choice of his own will, freely. Of his own will he chose Jacob, yet unborn, to become the head of the chosen race, rather than Esau. Note that this election was not to eternal salvation, but to become the head of a people. As Moses, Samuel, and John the Baptist were raised up for a great work of God, so was Jacob.
