Apocalypse Explained#145
145. (Verse 17) He that hath an ear let him hear what the spirit saith unto the churches. That this signifies that he who understands should hearken to what Divine truth proceeding from the Lord teaches and says to those who belong to His church is evident from what was said and shown above (n. 14 and 108), where similar words are explained.
Arcana Coelestia#6847
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.
