Spiritual Experiences # 1974
1974. As for the meaning of "evening and morning," in all phases of regeneration, both general and particular, the progression starts from evening, and tends toward morning. In general, the evening of those who are being regenerated is misery, temptations, despair, but they arrive at the morning. So also in detail, in all phases of regeneration one begins from evils, which are turned into good. And it is worth remembering that evil spirits begin, out of their own fantasies and passions, to arouse the person, but that these evils are turned into good in various ways. This has been revealed to me by experience lasting 3 years. So that is "evening and morning," and it applies to every least phase. Therefore it is the process not only of regeneration, but also of the perception of goodness. 1748, 16 May.
Arcana Coelestia # 2003
2003. 'As for Me, behold, My covenant is with you' means union of the Divine Essence with the Human Essence. This is clear from the meaning of 'a covenant' as conjunction, dealt with in 665, 666, 1023, 1038. Here it is the union of the Divine Essence with the Human Essence, as is evident from this meaning and from the internal sense of what has gone before, and so from the actual words 'My covenant is with you'.
