Job 36:30

Though God is enveloped in the dark cloud, He is there encircled with His light, which, though the masses of waters cover Him, manifests itself to men's eyes in the lightning that shoots from the cloud and illumines it.

the bottom of the sea lit. the rootsof the sea, a singular figure, which must mean the deepsor recesses of the sea. The reference is no doubt to the masses of water in the thunder clouds which enshroud the Almighty, but the precise idea of the poet is uncertain. Either he must call the heavenly waters the "sea" (cf. Psalms 29:3), and mean by its "roots" its densest recesses; or if he refer to the sea on earth, his idea must be that it has been, as it were, drawn up from its bottom in cloud and vapour to form the pavilion of the Lord. This second idea has a certain extravagance which makes it less probable.
