Job 26:10

The verse reads,

He hath drawn as a circle a bound upon the face of the waters,

At the confines of light and darkness.

The second clause is literally; even to the confines of light with(or, by) darkness, i. e. as far as where the utmost bound of light borders with darkness. The idea seems to be this: around the surface of the earth flows the ocean ("the face of the waters"); upon this like a circle all around the earth the arch of heaven comes down; all within this bound is light, for the sun rises on one side of it and goes down at the other; beyond this circle lies the utter darkness. Comp. ch. Job 38:19 seq.
