7712. And one shall grope in thick darkness. That this signifies the density of falsity from evil, is evident from the signification of "groping in thick darkness," as being that falsities from evil are so dense that nothing of truth and good can be known, but if it is sought it is as if one gropes in thick darkness, and stumbles and pushes in every direction; therefore in Isaiah thick darkness is called "the driven thick darkness" (Isa. 8:22); and it is described in the same prophet:
We walk in thick darkness. We grope for the wall like the blind, yea, we grope as they that have no eyes; we stumble at noon day as in the twilight; among the living we are as the dead (Isa. 59:9-10).
