In general, birth order in the Bible reflects the progression of spiritual states, but the specifics of those states depends greatly on context: who the people in question are, and whether we’re talking about spiritual states as they flow to us from the Lord, or spiritual states as we advance through them to approach the Lord. For example, Esau was older than Jacob (by minutes, but it mattered), and as the elder represents a more internal spiritual state: the desire for good, and the ideas that flow from that desire. Jacob represents a more external state: the understanding of ideas that lead to good. The switched blessing, with Jacob getting the blessing Isaac meant for Esau, shows that to progress in life we need to put our understanding first for a while, though ultimately our loves will catch up and ultimately determine our true character. A similar thing happens when Jacob crosses his hands to give Ephraim, the younger of Joseph’s sons, the primary blessing over his older brother Manasseh. Both those cases describe blessings coming from the Lord, with the highest states coming from Him and extending down through lower states to get to us. There is a sort of opposite dynamic in the story of Leah and Rachel. There Jacob (representing the Lord himself, as a human, in His childhood) is advancing from more external states to more internal ones. In this case, then, the older daughter, Leah, represents a more external state which He had to work through to reach the more internal state represented by Rachael.

5071. The reason why the expression 'cursed' is used of those on the left and why their punishment is called 'eternal fire' in the following statements -'Then He will also say to those on the left, Depart from Me, O cursed ones, into eternal fire prepared for the devil and his angels' and 'these will go away into eternal punishment' - is that they have turned away from good and truth and have turned towards evil and falsity. 'Cursing' in the internal sense of the Word means a turning away, 245, 379, 1427, 3570, 3584. The eternal fire into which they were to depart is not material fire, nor is it a tormented conscience, but a craving for evil. For cravings like this in a person are spiritual fires which consume him during the life of the body and torment him in the next life. Because of these fires burning within them, the inhabitants of hell use dreadful methods to torture one another.

[2] Eternal fire is clearly not material fire; and the reason it is not a tormented conscience is that none who are governed by evil have any conscience; and those who have had no conscience during their lifetime cannot have any in the next life. But the reason eternal fire is a craving is that the entire fire of life in a person is fuelled by his loves, a heavenly fire by the love of what is good and true, a hellish fire by the love of what is evil and false. Or what amounts to the same, a heavenly fire is fuelled by love to the Lord and love towards the neighbour, and a hellish fire by self-love and love of the world. Anyone can see, if he stops to think, that all the fire or heat burning within a person is fuelled by his loves. This also explains why love is called spiritual heat and why in the Word fire and heat have no other meaning, 934 (end), 1297, 1527, 1528, 1861, 2446, 4906. The fire of life in the evil is also such that when they feel very strong cravings, a kind of fire is also burning in them, which inflames them with an intense and furious desire to torment others. But the fire of life in the good is such that when a higher level of affection exists with them, a kind of fire is alight in them too. But this fire inflames them with a loving and zealous desire to do good to others.
