John Trapp on Isaiah 65:8

Ver. 8. Thus ſaith the Lord] This he ſaith in effect, I will not deſtroy the righteous with the wicked, but ſtill reſerve a ſeed, a remnant: and this he ſetteth forth by a fine and fit compariſon; even as the husbandman, if he find any wine in the cluſter, that is, any life or ſap in the vine, cutteth it not down utterly.

So will I do for my ſervants ſake] Few though they be, even as one cluſter of grapes upon a vine, yet becauſe they are botri muſtei, cluſters full of new and ſweet wine, full of the juyce of piety, they ſhall be preſerved.
