'Covering' in the Bible

And he, as a bridegroom, goeth out from his covering, He rejoiceth as a mighty one To run the path.

Covering himself with light as a garment, Stretching out the heavens as a curtain,

He hath spread a cloud for a covering, And fire to enlighten the night.

Who is covering the heavens with clouds, Who is preparing for the earth rain, Who is causing grass to spring up on mountains,
