Charles Ellicott Commentary Isaiah 66:22

"For as the new heavens and the new earth, which I will make, shall remain before me, saith Jehovah, so shall your seed and your name remain." — Isaiah 66:22 (ASV)

As the new heavens and the new earth ... —The transformation of Isaiah 65:17 is presupposed, but that future kingdom of God will perpetuate the historical continuity of what has preceded it. Israel (the prophet’s range of vision seems limited to the outward Israel, while St. Paul extends it to the spiritual) will still exist. The ideal represented by that name will have an indestructible vitality.
