Wisdom 17:6

6 Nothing was shining through to them except a dreadful, self-kindled fire, and in terror they deemed the things that they saw to be worse than that unseen appearance.

Wisdom 17:6 In-Context

4 For not even the inner chamber that held them protected them from fear, but terrifying sounds rang out around them, and dismal phantoms with gloomy faces appeared.
5 And no power of fire was able to give light, nor did the brilliant flames of the stars avail to illumine that hateful night.
6 Nothing was shining through to them except a dreadful, self-kindled fire, and in terror they deemed the things that they saw to be worse than that unseen appearance.
7 The delusions of their magic art lay humbled, and their boasted wisdom was scornfully rebuked.
8 For those who promised to drive off the fears and disorders of a sick soul were sick themselves with ridiculous fear.
