Ecclesiastes 1:3-7

What do people really gain from all the hard work they do here on earth? People live, and people die, but the earth continues forever. The sun rises, the sun sets, and then it hurries back to where it rises again. The wind blows to the south; it blows to the north. It blows from one direction and then another. Then it turns around and repeats the same pattern, going nowhere. All the rivers flow to the sea, but the sea never becomes full.
