Job 37:18 in the King James Version
Hast thou with him spread out the sky, which is strong, and as a molten looking glass?
Context
17 You whose clothing is warm when the earth is still by reason of the south wind?
18 Can you, with him, spread out the sky, which is strong as a cast metal mirror?
19 Teach us what we will tell him, for we can’t make our case by reason of darkness.
