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.

That 'these are the generations of the sons of Noah' means derivative matters of doctrine and derivative forms of worship in the Ancient Church, which in general is Noah, is clear from the meaning of 'generations', dealt with already. In the external or literal sense, generations involve one being begotten from another, as is well known; but in the internal sense everything has regard to things that are celestial and spiritual, that is, to what are matters of charity and of faith. Thus 'generations' here means things of the Church, and therefore matters of doctrine, as will be better evident from what follows.
