Verses 17-20
Job 37:17-20 17 Thou whose garments became hot,
When the land is sultry from the south: 18 Dost thou with Him spread out the sky,
The strong, as it were molten, mirror? 19 Let us know what we shall say to Him! -

Elsewhere the hemispheric firmament, which spans the earth with its sub-celestial waters, is likened to a clear sapphire Exo 24:10, a covering Psa 104:2, a gauze Isa 40:22; the comparison with a metallic mirror (מוּצק here not from צוּק, Job 37:10; Job 36:16, but from יצק) is therefore to be understood according to Petavius: Coelum aëreum στερέωμα
