Arcana Coelestia #5375
5375. 'To Joseph' means where the celestial of the spiritual was. This is clear from the representation of 'Joseph' as the celestial of the spiritual, often dealt with already. The celestial of the spiritual is the good of truth from the Divine.
Isaiah 10:21-23
21
A remnant will return, even the remnant of Jacob, to the mighty God.
22
For though your people, Israel, are like the sand of the sea, only a remnant of them will return. A destruction is determined, overflowing with righteousness.
23
For the Lord, Yahweh of Armies, will make a full end, and that determined, in the midst of all the earth.
