Ecclesiastes 1:7

All the rivers flow into the sea,
Yet the sea is not full.
To the place where the rivers flow,
There they flow again.

And I placed boundaries on it
And set a bolt and doors,

You covered it with the deep as with a garment;
The waters were standing above the mountains.

Treasury of Scripture Knowledge

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.

And I

placed boundaries on it

And set a bolt and doors,

You covered it with the deep as with a garment;
The waters were standing above the mountains.

Then God said, “Let the waters below the heavens be gathered into one place, and let the dry land appear”; and it was so.

For there are many words which increase futility. What then is the advantage to a man?
