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.

245. 'He said to the serpent, Cursed are you, more than every beast and more than every wild animal of the field' means that the sensory part turned away from the heavenly and towards the bodily, and in so doing brought condemnation, that is, a curse, upon itself. This becomes quite clear from the internal sense of the Word. Jehovah God or the Lord never curses anyone, is never angry with anyone, never leads anyone into temptation, and never punishes, let alone curses anybody. It is the devil's crew who do such things. Such things cannot possibly come from the fountain of mercy, peace, and goodness. The reason why here and elsewhere in the Word it is said that Jehovah God not only turns His face away, is angry, punishes, and tempts, but also slays and even curses, is that people may believe that the Lord rules over and disposes every single thing in the whole world, including evil itself, punishments, and temptations. And after people have grasped this very general concept, they may then learn in what ways He rules and disposes, and how He converts into good the evil inherent in punishment and the evil inherent in temptation. In teaching and learning the Word very general concepts have to come first; and therefore the sense of the letter is full of such general concepts.
