Theodoret of Cyrus, on Isa 51:6

“Lift up your eyes to heaven, and look down to the earth beneath: for the heavens shall vanish like smoke, and the earth shall be worn away like a garment, and the inhabitants thereof shall perish in like manner: but my salvation shall be for ever, and my justice shall not fail.”

“From the sky and the earth, from the things on high and those below, learn of my power. I produced these elements with great ease and, conversely, I can make them disappear. "But my salvation shall be for eternity, and my righteousness shall not fail." This is what the Lord has likewise said in the holy Gospels: "Heaven and earth shall pass away, but my words will by no means pass away."”
