Who coverest [thyself] with light as [with] a garment: who stretchest out the heavens like a curtain:
Ver. 2. Who coverest thyself with light] That lovely creature that first shone out of darkness, and is chief among all things sensible, as coming nearest to the unapproachable glory of God; like as the robe royal is next unto the king. Herod upon a set day came forth arrayed in royal apparel, in cloth of silver, saith Josephus, which being beaten upon by the sun's beams, dazzled the eyes of the people, and drew from them that blasphemous acclamation, Acts 12:21. God, when he made the world, showed himself in all his royalty; neither can we ascribe too much unto him.
Who stretchest out the heavens like a curtain] The whole expanse or firmament is as a canopy over God's throne, or rather as a curtain or screen between us and the Divine majesty, the sight whereof we cannot bear.
