Ecclesiastes 1:6-8

⁶The wind goeth toward the south, and turneth about unto the north; it turneth about continually in its course, and the wind returneth again to its circuits.

⁷All the rivers run into the sea, yet the sea is not full; unto the place whither the rivers go, thither they go again.

⁸All things are full of weariness; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing.
