'Hoping' in the Bible

And after working the earth of it with a spade, he took away its stones, and put in it a very special vine; and he put up a watchtower in the middle of it, hollowing out in the rock a place for the grape-crushing; and he was hoping that it would give the best grapes, but it gave common grapes.

Is there anything which might have been done for my vine-garden which I have not done? why then, when I was hoping for the best grapes did it give me common grapes?
