1330. That 'these are the generations of Shem' means the derivatives of the second Ancient Church is clear from the meaning of 'generations' as the origin and derivation of forms of doctrine and of worship, as stated already in 1145. Here and elsewhere in the Word 'generations' are nothing other than the things that constitute the Church, thus forms of doctrine and of worship. The internal sense of the Word encompasses nothing else. Consequently when any Church is born the generations of it are mentioned, as with the Most Ancient Church in Genesis 2:4, 'These are the generations of the heavens and of the earth'; and likewise with the other Churches that succeeded it before the Flood, 'This is the book of the generations', Genesis 5:1. The same is true of the Churches after the Flood which were three in number - the first called Noah, the second taking its name from Eber, the third from Jacob and subsequently from Judah and Israel. Verse 1 of the previous chapter, where the first Church is described, starts in similar fashion, 'These are the generations of the sons of Noah', as does the present verse in reference to this second Church taking its name from Eber, 'These are the generations of Shem', and in reference to the third as well, in verse 27 below, 'These are the generations of Terah'. Consequently 'generations' means nothing other than the origins and derivatives of forms of doctrine and of worship in the Church that is being described. The reason why the generations of this second Ancient Church are traced back to Shem, that is, why its beginning is described from Shem onwards, is that 'Shem' means internal worship, here the internal worship of this Church. Not that the nature of the internal worship of this Church was the same as that meant by 'Shem' in the previous chapter, but only that it is the internal worship of this Church.

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.
