Arcana Coelestia #4123
4123. A way of seven days. That this signifies the holy of truth, is evident from the signification of a “way,” as being truth (n. 627, 2333); and from the signification of “seven,” as being what is holy (n. 395, 433, 716, 881). Here the signification is that there was the ardor of conjunction, that is, of conjoining itself with the holy of truth.
Revelation 15:6-8
6
The seven angels who had the seven plagues came out, clothed with pure, bright linen, and wearing golden sashes around their breasts.
7
One of the four living creatures gave to the seven angels seven golden bowls full of the wrath of God, who lives forever and ever.
8
The temple was filled with smoke from the glory of God, and from his power. No one was able to enter into the temple, until the seven plagues of the seven angels would be finished.
