Ecclesiastes 1:6-8

Revised Standard Version Catholic Edition

⁶ The wind blows to the south,
    and goes round to the north;
round and round goes the wind,
    and on its circuits the wind returns.
⁷ All streams run to the sea,
    but the sea is not full;
to the place where the streams flow,
    there they flow again.
⁸ All things are full of weariness;
    a man cannot utter it;
the eye is not satisfied with seeing,
    nor the ear filled with hearing.
