   47 But what could I have done more in my vineyard? Have I slackened mine hand, that I have not nourished it? Nay, I have nourished it, and I have digged about it, and I have pruned it, and I have dunged it; and I have stretched forth mine hand almost all the day long, and the end draweth nigh. And it grieveth me that I should hew down all the trees of my vineyard, and cast them into the fire that they should be burned. Who is it that has corrupted my vineyard?
