3860. 'Leah conceived and bore a son' means spiritual conception and birth from what is external to what is internal. This is clear from the meaning of 'conceiving and bearing' in the internal sense as being regenerated, for a person who is being regenerated is conceived and born anew. Regeneration is for' this reason called rebirth, but that rebirth is spiritual. A person is indeed born a human being from his parents, but he does not become truly human until he is born again from the Lord. Spiritual and celestial life is what makes a person truly human, for that life distinguishes him from animals. This conception and birth is what is meant in the Word by the conceptions and births of all who are mentioned there, and by the words used here, 'Leah conceived and bore a son'. As to its being the generations and births of faith and love that are meant, see 613, 1145, 1255, 2020, 2584, 3856. Those conceptions and births take place from what is external to what is internal, and this is meant by 'Leah conceived and bore', for 'Leah' represents the affection for external truth, 3793, 3819, and 'Reuben' the truth of faith, which is the first stage of regeneration and the external from which it begins. The implications of all this will be evident from all that follows regarding Jacob's children by Leah and by Rachel.

1255. That 'according to their generations' means insofar as they were capable of being reformed is clear from the meaning of 'a generation' as reformation. When someone is born again or regenerated by the Lord, every single thing he receives anew is in that case a generation. So also here, since the Ancient Church is the subject, 'generations' means insofar as they were capable of being reformed. As for the reformations of these nations, the latter did not all have the same form of worship, nor did they all have the same doctrine, the reasons being that they were not all of the same disposition, and had not all been brought up in the same ways and from early childhood been taught the same things. The Lord in no way destroys the basic attitudes a person acquires from early childhood, but modifies them. And if these are held sacred by the person and are such as do not stand contrary to Divine and natural order but are in themselves of little importance, the Lord lets them alone and allows them to remain with that person, as He did with many things in the second Ancient Church, which things will in the Lord's Divine mercy be dealt with later on.
