(18) Spread out the sky.--Some understand this of the action of the sun in dispersing the clouds; but it seems more probable that it refers to God. "Hast thou spread out with Him the magnificent dome of heaven?" The words used, however, imply the clouds rather than the cloudless sky which resembles a burnished mirror; so that it is not improbable that the sun may be the subject here and in the following verses.

Verse 18. - Hast thou with him spread out the sky? Didst thou assist in the spreading out of the sky, that great and magnificent work of the Creator, transcending almost all others (see the comment on Job 9:8)? Or did not God effect this work alone, without even a counsellor (Isaiah 40:13, 14), so that thou hadst no part in it? Which is strong, and as a molten looking-glass. The sky is "strong" or "firm;" i.e. enduring or permanent, though not really hard like a mirror. Elihu, however, seems to have regarded it, like many of the ancients, as a solid mass, resembling a concave mirror of metal. The translation, "looking-glass," is wrong, both here and in Exodus 38:8, since glass was not used for mirrors until the period of the early Roman empire. The earlier mirrors were of polished metal (see Smith's 'Dict. of Antiquities,' vol. 3. pp. 1052, 1212).

37:14-20 Due thoughts of the works of God will help to reconcile us to all his providences. As God has a powerful, freezing north wind, so he has a thawing, composing south wind: the Spirit is compared to both, because he both convinces and comforts, So 4:16. The best of men are much in the dark concerning the glorious perfections of the Divine nature and the Divine government. Those who, through grace, know much of God, know nothing, in comparison with what is to be known, and of what will be known, when that which is perfect is come.Hast thou with him spread out the sky?.... Wast thou concerned with him at the first spreading out of the sky? wast thou an assistant to him in it? did he not spread it as a curtain or canopy about himself, without the help of another? verily he did; see Job 9:8, Isaiah 44:24;

which is strong: for though it seems a fluid and thin, is very firm and strong, as appears by what it bears, and are contained in it; and therefore is called "the firmament of his power", Psalm 150:1;

and as a molten looking glass; clear and transparent, like the looking glasses of the women, made of molten brass, Exodus 38:8; and firm and permanent (u); and a glass this is in which the glory of God, and his divine perfections, is to be seen; and is one of the wondrous works of God, made for the display of his own glory, and the benefit of men, Psalm 19:1. Or this may respect the spreading out a clear serene sky, and smoothing it after it has been covered and ruffled with storms and tempests; which is such a wonderful work of God, that man has no hand in.
