All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing.Ecclesiastes 1:8 KJV
The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.Ecclesiastes 1:6 KJV
