'Ago' in the Bible

Is there a thing of which it may be said, "Behold, this is new?" It has been long ago, in the ages which were before us.

I turned myself to consider wisdom, madness, and folly: for what can the king's successor do? Just that which has been done long ago.

That which is has been long ago, and that which is to be has been long ago: and God seeks again that which is passed away.

Whatever has been, its name was given long ago; and it is known what man is; neither can he contend with him who is mightier than he.

Also their love, their hatred, and their envy has perished long ago; neither have they any more a portion forever in anything that is done under the sun.
