In the beginning, O Lord, you laid the foundations of the earth,
and the heavens are the work of your hands.
They will perish, but you remain;
they will all wear out like a garment.
You will roll them up like a robe;
like a garment they will be changed.

The heavens and earth will be rolled up and discarded, in the way that clothes are changed.

The old clothes that have perished are thrown away, and replaced with new clothes.

The old clothes are rolled up and thrown away.

As I said, Wright is very good on explaining this ‘clothing’ metaphor, which many people cannot understand.
