6847. 'The God of Abraham, the God of Isaac, and the God of Jacob' means the Divine itself and the Divine Human, thus the Lord. This is clear from the representation of 'Abraham, Isaac, and Jacob' as the Lord's Divine itself and His Divine Human. For the fact that 'Abraham' represents the Lord's Divine itself, 'Isaac' His Divine Rational, and 'Jacob' His Divine Natural, see 1893, 2011, 2066, 2072, 2083, 2630, 3194, 3210, 3245, 3251, 3305 (end), 3439, 3704, 4180, 4286, 4538, 6425, 6804. By 'God' is meant that which is Divine, and by those three names that which is representative; therefore those attributes within the Lord are what 'the God of Abraham, the God of Isaac, and the God of Jacob' is used to mean.

2066. 'And I will also give you a son by her' means the Rational. This is clear from the meaning of 'a son' as truth, dealt with in 489, 491, 533, 1147. And because the whole of the rational originates in truth, 'a son' here means the rational. The Lord's first rational was represented and meant by Ishmael, born from the servant-girl Hagar. This was dealt with previously in Chapter 16. The second Rational, which is the subject here, is represented and meant by Isaac who was to be born from Sarah. The former, that represented by Ishmael, was the rational that was subsequently cast out of the house, but this latter Rational, which is represented by Isaac, is the one that remained in the house, because it was Divine. This rational is in the Lord's Divine mercy to be described in the next chapter where Isaac is the subject.
