John Trapp on Job 9:8

Verſe 8. Which alone ſpreadeth out the heavens] Without the help or counſel of any other. As God was alone and by himſelf in making the world, Iſa. 44.24. ſo lie is in ordering it, Job 37.18. Pſalm 104.1, 2. The Hebrews, as they held with Pythagoras in the point of tranſanimation; ſo with Plato in that falſe opinion of his, that the Angels were the movers of the heavens, and the governours of the whole world; whence grew that Angel-worſhip amongſt them, Col. 2.18. As God made the heavens alone, even that whole Expanſe or Firmament, Gen. 1.6. the whole region of the Ayre; ſo he ſtill ſpreadeth it out as a curtaine, which he draweth before the Sun and ſtarres, masking and muffling them up with clouds, whenſoever he pleaſeth.

And treadeth upon the waves of the ſea] Or, ſpurneth, exerciſing a regiment over the raging ſurges of the ſeas, though they ſeem to ſwell againſt him. Thus Job fetcheth evidences of Gods power from all places. See Pſalm 89.9.
