11 And I, even I, turned toward all the works of mine that my hands had done and toward the hard work that I had worked hard to accomplish,+ and, look! everything was vanity and a striving after wind,+ and there was nothing of advantage under the sun.+

8 There exists one, but not a second one;+ also no son or brother does he have,+ but there is no end to all his hard work. Also, his eyes themselves are not satisfied with riches:+ “And for whom am I working hard and causing my soul to lack in good things?”+ This too is vanity, and it is a calamitous occupation.+
