'Fruit' in the Bible

I designed royal gardens and parks for myself, and I planted all kinds of fruit trees in them.

So I loathed all the fruit of my effort, for which I worked so hard on earth, because I must leave it behind in the hands of my successor.

Who knows if he will be a wise man or a fool? Yet he will be master over all the fruit of my labor for which I worked so wisely on earth! This also is futile!

So I began to despair about all the fruit of my labor for which I worked so hard on earth.

For a man may do his work with wisdom, knowledge, and skill; however, he must hand over the fruit of his labor as an inheritance to someone else who did not work for it. This also is futile, and an awful injustice!

God gives a man riches, property, and wealth so that he lacks nothing that his heart desires, yet God does not enable him to enjoy the fruit of his labor -- instead, someone else enjoys it! This is fruitless and a grave misfortune.
