²¹ People can work hard using all their wisdom, knowledge, and skill, but they will die, and other people will get the things for which they worked. They did not do the work, but they will get everything. This is also unfair and useless. ²² What do people get for all their work and struggling here on earth? ²³ All of their lives their work is full of pain and sorrow, and even at night their minds don’t rest. This is also useless.
