Matthew Poole and continuators on Hebrews 1:11

11 They shall perish , but thou remainest : and they all shall wax old as doth a garment .

The Heavens themselves instanced in, as containing the most excellent part of the Creation (such as the Gentile Philosophy esteemed incorruptible) are mutable, as by the various Changes, not only in the Aery part of it, but in the Aetherial, doth appear: The glorious Lights in it have their spots and rusts, as the Sun it self, both increasing and diminishing upon them, and so as to their present, natural frame, are changeable, perishable and dissolvable, Isa. 51.6. Matth. 24.35.

But the Son Iehovah is unchangeable, hath a stedfast. Being, such as never loseth its state, no Term is set for the ending of him. His Immutability proves his Deity. Remainest is an expression of present Time, denoting constant abiding. He was before, in, and after all Ages immutable, Lam. 5.19. chap. 13.8. Iesus Christ, the same yesterday, this day, and for ever.

The Antiquation of a Garment is a Metaphor borrowed, to shew the corruptibility of the Heavens; A Garment wears and decayeth with use in a tract of Time, it changeth its Fashion, is another thing as to its matter and form: so will the Heavens, as to their form and face decay, they are gradually coming to an end as to what they are now, 2 Pet. 3.7, 10. That which decayeth and waxeth old, is ready to vanish away; so these Heavens do, chap. 8.13.
