It upholds the Calvinist viewpoint right up till you look at the Scripture in context. It is a quote from Malach1 1
Alright, lets suppose for one minute, that you are correct and it was meant to address "Israel and Edom."
Who in Romans 9 is Edom?
The Jews again? (Edom were/are desendants of Esau, who was a desendant of Iaasc)
No, it is a picture of "election" in the Old Testament.
Election was as much a reality in the OT era as it is today.
Why did God choose Israel?
"For thou
art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that
are upon the face of the earth.
The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people: But because the LORD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt." -Deut. 6:6-8 (KJV)
God did not "foresee" anything that Israel would or would not do. Simply because He chose to, because He loved them, and to fulfill His promise to Abraham.
"I have loved you, saith the LORD. Yet ye say, Wherein hast thou loved us?
Was not Esau Jacob's brother? saith the LORD: yet I loved Jacob," -Mal. 1:2 (KJV)
"I have loved you, saith the Lord,.... Which appeared of old, by choosing them, above all people upon the face of the earth, to be his special and peculiar people; by bestowing peculiar favours and blessings upon them, both temporal and spiritual; by continuing them a people, through a variety of changes and revolutions; and by lately bringing them out of the Babylonish captivity, restoring their land unto them, and the pure worship of God among them:
Yet ye say, wherein hast thou loved us? the Targum renders it, "and if ye should say"; and so Kimchi and Ben Melech; which intimates, that though they might not have expressed themselves in so many words, yet they seemed disposed to say so; they thought it, if they said it not; and therefore, to prevent such an objection, as well as to show their ingratitude, it is put in this form; and an instance of his love is demanded, which is very surprising, when they had so many; and shows great stupidity and unthankfulness. Abarbinel renders the words, "wherefore hast thou loved us?" that is, is there not a reason to be given for loving us? which he supposes was the love of Abraham to God; and therefore his love to them was not free, but by way of reward to Abraham's love; and consequently they were not so much obliged to him for it: to which is replied, was not Esau Jacob's brother? saith the Lord; Jacob and Esau were brethren; they had one and the same father and mother, Isaac and Rebekah, and equally descended from Abraham; so that if one was loved for the sake of Abraham, as suggested, according to Abarbinel's sense, the other had an equal claim to it; they lay in the same womb together; they were twins; and if any could be thought to have the advantage by birth, Esau had it, being born first: but before they were born, and before they had done good or evil, what is afterwards said of them was in the heart of God towards them; which shows that the love of God to his people is free, sovereign, and distinguishing,
Genesis 25:23, yet I loved Jacob; personally considered; not only by giving him the temporal birthright and blessing, and the advantages arising from thence; but by choosing him to everlasting life, bestowing his grace upon him, revealing Christ unto him, and making him a partaker of eternal happiness; and also his posterity, as appears by the above instances mentioned; and likewise mystically considered, for all the elect, redeemed, and called, go by the name of Jacob and Israel in Scripture frequently; for what is here said of Jacob is true of all the individuals of God's people; for which purpose the apostle refers to this passage in
Romans 9:13, to prove the sovereignty and distinction of the love of God in their election and salvation: and this is indeed a clear proof that the love of God to his people is entirely free from all motives and conditions in them, being before they had done either good or evil; and therefore did not arise from any goodness in them, nor from their love to him nor from any good works done by them: the choice of persons to everlasting life, the fruit of this love, is denied to be of works, and is ascribed to grace; it passed before any were wrought; and what are done by the best of men are the effects of it; and the persons chosen or passed by were in an equal state when both were done; which appears by this instance: and by which also it is manifest that the love of God to men is distinguishing; it is not alike to all men; there is a peculiar favour he bears to own people; which is evident by the choice of some, and not others; by the redemption of them out of every kindred, tongue, people, and nation; by the effectual calling of them out of the world; by the application of the blessings of grace unto them; and by bestowing eternal life on them: and it may be further observed, that the objects of God's love have not always the knowledge of it; indeed they have no knowledge of it before conversion, which is the open time of love; and after conversion they have not always distinct and appropriating views of it; only when God is pleased to come and manifest it unto them."

Election in the Old Testament, is the same "election" in the New Testament.
And it certainly was not based upon, or was conditional on anything any individual, or class of people would or would not do.
God Bless
Till all are one.
