180. Verse 29. He that hath an ear let him hear what the Spirit saith unto the churches, signifies that he who understands should hearken to what Divine truth proceeding from the Lord teaches and says to those who are in His church, as is evident from what was said and shown above n. 108, where there are like words.
Arcana Coelestia # 3458
3458. 'And in the morning they rose up early' means a state of enlightenment. This is clear from the meaning of 'the morning' and 'rising up early' as a state of enlightenment. For by 'the morning' and 'the dawn' in the highest sense is meant the Lord, and in the internal sense the celestial element of His love, and also from this the state of peace, see 2333, 2405, 2540, 2780. And 'rising up' means in the internal sense a raising up, 2401, 2785, 2912, 2927, 3171. From these meanings it is evident that 'in the morning he rose up early' means a state of enlightenment.
