Rom 9:11 does not say that they did no evil before they were born - it says that before they were born or ever did any evil
in this life after their birth, one was
already chosen / elected to lead and one to follow because HE loved the one and the other HE hated...to prove election was not by works but by HIS will.
11Yet before the twins were born or had done anything good or bad, in order that God’s plan of election might stand, 12not by works but by Him who calls, she was told, “The older will serve the younger.”d 13So it is written: “Jacob I loved, but Esau I hated.”
Many have rigorously rejected the notion that GOD would hate an innocent before he sinned. Since they were being evil in the womb the time before they had done anything good or bad must have been before their conception when we were all spirits made in the image of GOD being separated by our free will faith decisions into the elect whom HE loved or the non-elect whom HE hated.
Election was NOT unconditional or reprobation was also non-conditional which denigrates the loving kindness of GOD. The condition for election was having faith in YHWH's proclamation to be our creator GOD and the only saviour from sin,
Col 1:23, while the condition for reprobation was to rebuke YHWH by faith, not proof, as a liar and therefore a false god, the unforgivable sin, the Satanic fall before the foundation of the world.
