What does expanding a proverb mean?
If you mean by adding more details then I strongly suggest you
lease well alone, you may alter the whole meaning of the proverb.
My suggestion is to fully understand what the writer is saying.
There may be symbolic meanings in the work that need to be
understood. Certain phrasings may need to be comprehended, for what
was meant when the proverb was written may not mean the same thing
today. Who is the proverb talking to and does it apply to you.
