5160. 'On Pharaoh's birthday' means when the natural was to be regenerated. This is clear from the meaning of 'being born' as being regenerated, dealt with below; and from the representation of 'Pharaoh' as the interior natural, dealt with in 5080, 5095, in this case the natural in general because among regenerate persons the agreement of the interior natural with the exterior natural causes the two to act as one. The reason 'being born' means being regenerated is that in the internal sense spiritual matters are meant, and spiritual birth is regeneration, which is also called rebirth. When therefore birth is spoken of in the Word no other birth is understood in heaven than a birth effected through water and the spirit, that is, through faith and charity. For being born again or regenerated makes a person truly human and entirely different from animals, because in this case he becomes a son and heir of the Lord's kingdom. As regards the births which are mentioned in the Word meaning spiritual births, see 1145, 1255, 3860, 3868, 4070, 4668.

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.
