Ecclesiastes 4:7-8

⁷Then I turned and saw other vanity under the sun.

⁸There is one who is alone, and no one with him; yea, he hath neither son nor brother; yet is there no end to all his labor, and his eye is not satisfied with riches. “For whom, then saith he, do I labor and deprive myself of good?” This also is vanity; yea, it is an evil thing!
