Arcana Coelestia #87
87. Another reason why the celestial man is the Sabbath or rest is that conflict ceases when he becomes celestial. Evil spirits withdraw and good spirits approach, as do celestial angels. When these are present evil spirits cannot possibly be present too, but flee far away. And because it was not the person himself who fought but the Lord alone on his behalf, it is said that 'the Lord rested'.
Isaiah 61:10
10
I will greatly rejoice in Yahweh, my soul shall be joyful in my God; for he has clothed me with the garments of salvation, he has covered me with the robe of righteousness, as a bridegroom decks himself with a garland, and as a bride adorns herself with her jewels.
