4641. 'These are the generations of Esau' means the derivatives within the Lord's Divine Natural Good. This is clear from the meaning of 'generations' as derivatives, that is to say, derivatives of good and truth, dealt with in 1330, 3263, 3279, 3860, 3868, 4070, and from the representation of 'Esau' as the Lord's Divine Natural Good, dealt with in 3302, 3322, 3494, 3504, 3576, 3599. This Good is the subject now in this chapter. But because its nature is such that it does not come within the range of understanding which any man possesses, and scarcely within that of any angel, mere names are therefore used to describe this Good. The Lord's Divine Natural Good represented by 'Esau' is that which was Divine and which He had from when He was born; for He had been conceived from Jehovah and therefore had what was Divine even from birth. It existed in Him as His soul and was consequently the central core of His life.

[2] Outwardly this had been clothed with what He took upon Himself from His mother. But since that which He took from her was not good but essentially evil, He cast this out by means of His own power, in particular by means of the conflicts that came with temptations. Then after that He joined this Human which He made new within Himself to the Divine Good which He had had from when He was born. 'Jacob' represented the good which He acquired to Himself by His own power and which has been the subject in the chapters immediately before the present one. This acquired good is what He joined to the Divine Good; and in this way He made the entire Human within Him Divine. The Good which 'Esau' represents was coming in by an internal route, through rational good directly into the Natural. But the good which 'Jacob' or 'Israel' represents was coming in by an external route to be met by the Divine coming through rational good, though indirectly through the truth of the Rational into the Natural. 'Isaac' represents the rational good, and 'Rebekah' the rational truth; see what has been stated already concerning them in 3334, 3573, 4563 (end).

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.
