All streams flow into the sea, yet the sea is never full. To the place the streams come from, there they return again.
All things are wearisome, more than one can say. The eye never has enough of seeing, nor the ear its fill of hearing.Ecclesiastes 1:8 NIV
The wind blows to the south and turns to the north; round and round it goes, ever returning on its course.Ecclesiastes 1:6 NIV
