Verse 17 (Isa 65:17) looks beyond the kingdom-age to the new heavens and the new earth (see refs. At "create"), but verses 18-25 (Isa 65:18-25) describe the kingdom-age itself. Longevity is restored, but death, the "last enemy" (Co1 15:26) is not destroyed till after Satan's rebellion at the end of the thousand years. (Rev 20:7-14).
