That I know nothing about it. Just outside my interests and

I do not know. May there be a special discussion group with focus

I am sure that given time I'll be able to point you to several
pages in Talmud where the saying appears just as "vedai lhaham."

I do not know where the original saying comes from.

The saying is addressed to a reader. As I said, it often
appears in talmud in the short version. It says nothing
of the background, but just terminates some words of wisdom.

You may want to check this with a rabbi in your neighborhood.
