Who coverest thyself with light as with a garment: who stretchest out the heavens like a curtain:
Who coverest thyself with light as with a garment. The general glory put on by God as a garment at creation is here transferred to one department-namely, the calling forth of light, with which creation began. The light meant is not that "light which no man can approach unto" (1 Timothy 6:16), but that which was first unfolded at creation, and which daily illuminates us (Genesis 1:3). The Hebrew participles imply continued action. God perpetuates in His daily providence the work which He originated at creation.
Who stretchest out the heavens like a curtain - like the covering spread over a tent, as the tabernacle. God did so on the second day by His word with the same ease with which one stretches out a tent-curtain (Isaiah 54:2; Isaiah 40:22).
