'Dark' in the Bible

seek him that made the Pleiades and Orion, and turneth the shadow of death into the morning, and maketh the day dark with night; that calleth for the waters of the sea, and poureth them out upon the face of the earth: Jehovah is his name.

Shall not the day of Jehovah be darkness, and not light? even very dark, and no brightness in it?
