Esias 65:8

8 Thus saith the Lord, As a grape-stone shall be found in the cluster, and they shall say, Destroy it not; for a blessing is in it: so will I do for the sake of him that serves me, for his sake I will not destroy all.

Esias 65:8 In-Context

6 Behold, it is written before me: I will not be silent until I have recompensed into their bosom,
7 their sins and of their fathers, saith the Lord, who have burnt incense on the mountains, and reproached me on the hills: I will recompense their works into their bosom.
8 Thus saith the Lord, As a grape-stone shall be found in the cluster, and they shall say, Destroy it not; for a blessing is in it: so will I do for the sake of him that serves me, for his sake I will not destroy all.
9 And I will lead forth the seed of Jacob and of Juda, and they shall inherit my holy mountain: and mine elect and my servants shall inherit it, and shall dwell there.
10 And there shall be in the forest folds of flocks, and the valley of Achor be for a resting-place of herds for my people, who have sought me.
