Isaiah 65:18

18 Then be glad and rejoice forever in what I am creating; for I will create Jerusalem to be a joy, and its people to be a delight.

Isaiah 65:18 In-Context

16 Whoever is blessed in the land will be blessed by the God of truth, and whoever swears in the land will swear by the God of truth. For the former troubles will be forgotten and hidden from My sight.
17 "For I will create a new heaven and a new earth; the past events will not be remembered or come to mind.
18 Then be glad and rejoice forever in what I am creating; for I will create Jerusalem to be a joy, and its people to be a delight.
19 I will rejoice in Jerusalem and be glad in My people. The sound of weeping and crying will no longer be heard in her.
20 In her, a nursing infant will no longer live only a few days, or an old man not live out his days. Indeed, the youth will die at a hundred years, and the one who misses a hundred years will be cursed.
