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.

2780. 'In the morning Abraham rose up early' means a state of peace and innocence. This is clear from the meaning of 'in the morning', also of 'rising up in the early morning', when used in reference to the Lord, who is 'Abraham' here. 'The morning' in the universal sense means the Lord, and from this His kingdom. Consequently it means the celestial element of love in general and in particular, as shown in 2333. And as it means those things it means the state itself in which they exist, which state is one of peace and innocence. The state of peace in heaven is like that at dawn on earth. Within the state of peace in heaven all celestial and spiritual things manifest themselves, and from it they derive all their bliss, blessedness, and happiness, even as at dawn on earth when all things present themselves to man with a delightful and gladsome air, for each specific celestial or spiritual thing receives its character from the general affection, 920, 2384. The same applies to the state of innocence. This manifests itself within the state of peace and is something general and overall which brings itself to bear on all things of love and faith. Unless the latter possess innocence within them they lack their essential element. It is for this reason that nobody is able to enter heaven unless he possesses a measure of innocence, Mark 10:15. From this it is evident what 'in the morning' means in the internal sense, even more what is meant by the words 'in the morning he rose up early'. And since in the highest sense 'the morning' is the Lord, and He is the author of the state which brings into being and exerts an influence on the things that exist in His kingdom, 'in the morning' and 'rising up in the morning' also mean further things still which arise in that state and are related to the things that follow in the internal sense.
