Elihu speaks of the deep parts of the sea as if the sea were a plant and its depths were its roots. Possible meanings are 1) although the lightning causes light in the sky, the deep parts of the sea remain dark.

Alternate translation: "and lights up the depths of the sea" (See: rc://en/ta/man/translate/figs-metaphor)
