Genesis 25

As for those who prefer to read no symbolic meanings into such facts, they still have no ground of complaint against Abraham. For, in the literal sense, there may be meant to be here an argument against those heretics who are opposed to second marriages, since the example of the very father of many nations proves that there is no sin in a second marriage that is made after one's wife is dead.

We must now take a look at the history of the city of God, as it takes its course from this point on among the descendants of Abraham. In the period from Isaac's birth to his seventieth year, when his first children were born, there is one memorable fact: He asked God that his wife, who was barren, might bear him a child. God heard the prayer, and she conceived twins who leaped while still in her womb. She was troubled by the disturbance, and, asking the Lord, she received this answer: "Two nations are in your womb; two people shall stem from your body. One people shall be stronger than the other, and the elder shall serve the younger."This is interpreted by the apostle Paul as an obvious proof of the working of grace: "For before the children had yet been born or had done anything of good or evil," the younger was chosen, through no merits of his own, and the older rejected. So far as original sin goes, both were equal. As for personal sins, neither had any.

Two twins were born at so short an interval of time that the second had a hold on the foot of the first. Yet they were so unlike in their lives, character, conduct and the love their parents bore them that this unlikeness made them enemies one of the other. When I say unlike, I do not mean that one would sit while the other walked, or that one slept while the other was awake or that one talked while the other kept quiet.One of our twins led a life of servile toil, while the other served no one. One was loved by his mother; the other was not. One lost the title to primogeniture, which was then so highly esteemed, and the other obtained it. Further, there were immense differences between them in regard to their wives, children and possessions. If such differences are to be explained by those split seconds between the births of twins which are considered negligible in their horoscopes, why are such matters mentioned when other people's horoscopes are in question?
