Are you a sour grape? Are you a wild grape? Isaiah prophesied, and Jesus later used as His illustration of the ungrateful tenants in the parable of the landowner:
"Let me sing for my beloved my love song concerning his vineyard: My beloved had a vineyard on a very fertile hill. He dug it and cleared it of stones, and planted it with choice vines; he built a watchtower in the midst of it, and hewed out a wine vat in it; and he looked for it to yield grapes, but it yielded wild grapes."
