I observed all the work of God and concluded that man is unable to discover the work that is done under the sun. Even though a man labors hard to explore it, he cannot find it; even if the wise man claims to know it, he is unable to discover it.

When there is a man whose work was done with wisdom, knowledge, and skill, and he must give his portion to a man who has not worked for it, this too is futile and a great wrong.
