Ecclesiastes 1:6-8

⁶The wind goes to the south, turning back again to the north; circling round for ever.

⁷All the rivers go down to the sea, but the sea is not full; to the place where the rivers go, there they go again.

⁸All things are full of weariness; man may not give their story: the eye has never enough of its seeing, or the ear of its hearing.
