Isaiah 5:2, 4

First he dug up its ground and hauled away its stones so he could plant within it the choicest of vines. He built a watchtower in the middle of it and carved a winepress out of its rock. He fully expected it to bear good grapes, but instead it produced only worthless wild grapes.

What more could I have done for my vineyard? When I expected it to bear luscious grapes, why did it produce only wild, worthless grapes?
