And not only this; but when Rebecca also had conceived by one, even by our father Isaac; 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, It was said unto her, The elder shall serve the younger. As it is written, Jacob have I loved, but Esau have I hated.
Was the hardening of Esau "judicial"?
What verse are you referring to that talks about his being hardened? I'll take a look at it.
FYI / FWIW, it is consistent throughout the scriptures that it's actually the second born that obtains the favor of God, not the firstborn, i.e.,
Cain/Abel, Shem/Japheth, Ishmael/Isaac, Essau/Jacob, Mannassah/Ephraim, First/Second Wilderness Generations, Saul/David, First Covenant/Second Covenant, First Man Adam/Second Adam (and doubtless many others):
It was not Cain's sacrifice that God had respect for, but it was Abel's; 'Cain was of the evil one, and slew his brother....Because his works were evil, and his brother`s righteous.' [1 Jn 3:12]
Shem was the elder brother of Japheth, but, 'God enlarge Japheth, And let him dwell in the tents of Shem...' [Gen 10:21 ASV & 9:27]
It was Ishmael, the firstborn, that was born after the flesh, and he persecuted Isaac, the second born, that was born after the Spirit. Isaac was the child of promise; Ishmael was cast out. [Gal 4:29]
It was said of Esau and Jacob, 'The elder shall serve the younger. Even as it is written, Jacob I loved, but Esau I hated.' [Ro 9:12,13]
It was not Leah his first wife that Jacob loved, but it was Rachel his second wife. [Gen 29:30,31]
It was Ephraim the younger that Jacob blessed over his older brother Mannassah and in spite of Joseph's objections. [Gen 48:13-20]
It was not the first generation of the exodus that entered into the rest of the promised land, it was the second generation; 'But your little ones, that ye said should be a prey, them will I bring in, and they shall know the land which ye have rejected.' [Nu 14:31]
It was not Saul the first king of Israel that would do all of God's will, but it was the second king David that was a man after His heart; '...Saul the son of Kish...when he had removed him, he raised up David to be their king; to whom also he bare witness and said, I have found David the son of Jesse, a man after My heart, who shall do all My will.' [Acts 13:21,22]
It was not the first covenant of the law ( I desire mercy, and not sacrifice) that God had pleasure in, but it was the second covenant of grace; '....a better covenant, which hath been enacted upon better promises. For if that first covenant had been faultless, then would no place have been sought for a second.' [Heb 8:6,7]
Consider 'the first man Adam' vs. 'the last Adam, ' ... that is not first which is spiritual, but that which is natural; then that which is spiritual. The first man is of the earth, earthy: the second man is of heaven.' [1 Cor 15:45-47]
