Charles Ellicott Commentary 2 Chronicles 6:1

"Then spake Solomon, Jehovah hath said that he would dwell in the thick darkness." — 2 Chronicles 6:1 (ASV)

This section also is in verbal agreement with the parallel account, with a few slight exceptions.

1. The thick darkness. — ‘Araphel, which is explained as caligo nubium, “gloom of clouds.” (Deuteronomy 4:11; Psalms 18:9. Compare to the Greek, ὅρφνη.) The Targum on 1 Kings 8:12 reads Jerusalem, but this is probably a gloss.
