5348. 'And to Joseph were born two sons' means the good and truth born from this, that is to say, from the influx of the celestial of the spiritual into the natural. This is clear from the meaning of 'being born' as being reborn, and so the birth of truth derived from good or faith derived from charity, dealt with in 4070, 4668, 5160 (for the generations described in the Word are spiritual ones, see 1145, 1255, 1330, 3263, 3279, 3860, 3866); and from the meaning of 'sons', who in this case are Manasseh and Ephraim, as good and truth, dealt with immediately below. For 'Manasseh' means the area of will belonging to the new natural, while 'Ephraim' means the area of understanding belonging to it. Or what amounts to the same, 'Manasseh' means the good present in the new natural, since good exists as an attribute of the will, while 'Ephraim' means the truth present there, since truth exists as an attribute of the understanding. One reads in other places about the birth of two sons. Good is meant by one, truth by the other, as for instance with Esau and Jacob. 'Esau' means good, see 3302, 3322, 3494, 3504, 3576, 3599, while 'Jacob' means truth, 3305, 3509, 3525, 3546, 3576. The like is meant by Judah's two sons by Tamar, Perez and Zerah, 4927-4929; and the same applies here in the case of Manasseh and Ephraim. The birth of these is dealt with here because the subject in what went immediately before this was the influx of the celestial of the spiritual into the natural and the consequent rebirth of it, which is effected solely by means of good and truth.

3279. 'These are the generations of Isaac, Abraham's son' means the Lord's Divine Rational, from which the Divine Natural sprang. This is clear from the meaning of 'generations' as derivatives, dealt with in 1145, 1255, 1330, that is to say, derivatives of faith when faith is the subject, and derivatives of the Church when the Church is the subject, as above where derivatives of the spiritual Church are meant by the generations of Ishmael, 3263. Here however since 'generations' has reference to the Lord, Divine generations are meant. That is to say, the Divine Rational came into being from the Divine itself, which is meant by Isaac who was begotten by Abraham; and the Divine Natural came into being from the Divine Rational, which is meant by Esau and Jacob who were begotten by Isaac. For Esau and Jacob represent the Lord's Divine Natural, Esau as regards good, and Jacob as regards truth, both being dealt with in what follows next. These are the things meant here by 'generations'.
