'Bad' in the Bible

And he fenceth it, and casteth out its stones, And planteth it with a choice vine, And buildeth a tower in its midst, And also a wine press hath hewn out in it, And he waiteth for the yielding of grapes, And it yieldeth bad ones!

What -- to do still to my vineyard, That I have not done in it! Wherefore, I waited to the yielding of grapes, And it yieldeth bad ones!
