Ecclesiastes 1:7-8

Amplified Bible

⁷ 
All the rivers flow into the sea,
Yet the sea is not full.
To the place where the rivers flow,
There they flow again.
⁸ 
All things are wearisome and all words are frail;
Man cannot express it.
The eye is not satisfied with seeing,
Nor is the ear filled with hearing.^(A)
