Who coverest thyself with light as with a garment,.... Referring, as Aben Ezra and Kimchi think, to the light, which was first created; and indeed this was commanded out of darkness by God the Word, or by the essential Word of God.
Light is expressive of the nature of God himself, who is light, and in him is no darkness at all, and who dwells in light inaccessible, and so may be said to be clothed with it; which is applicable to Christ as a divine Person, 1Jo 1:5.
and to whom this term "light" well agrees; Light being one of the names of the Messiah in the Old Testament, Ps 43:3, and is often given him in the New Testament, as the author of the light of nature, grace, and glory, Joh 1:9.
He is now possessed of the light and glory of the heavenly state, of which his transfiguration on the mount was an emblem, when his face shone like the sun, and his raiment was as the light, Mt 17:2.Who stretchest out the heavens like a curtain; alluding to the firmament or expanse, which, being spread out like a curtain, divided between the waters and the waters, Ge 1:6.
