'Darkens' in the Bible

Look! The one who crafts mountains, who creates the wind, who reveals what he is thinking to mankind, who darkens the morning light, who tramples down the high places of the land the LORD, the God of the Heavenly Armies is his name.

Seek the one who fashions the Pleiades and Orion, who turns the deep darkness into morning, who darkens day into night, who calls out to the waters of the sea, pouring them out onto the surface of the earth the LORD is his name.
