Arcana Coelestia # 3785
3785. 'He said, Behold, it is still high day' means that the state was now in progress. This is clear from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, 3462, while the meaning of the words 'Behold, it is still high [day]' as in progress is evident from the train of thought.
