What’s the difference between ‘works of the law’ and ‘deeds of the law’?

The difference between the ‘works of the law’ and the ‘deeds of the law’?  I have my thoughts but as always want your thoughts and your knowledge on it.

“Deeds of the Law” seem to be the accomplished acts, the “Works of the Law” may be a reference to the efforts to keep the law.  There may or may not be a difference, however Israel who was under the law tried to fulfill the deeds of the law, but even people today, Gentiles who were never under the law, even religious people are attempting to do the works of the law in order to placate God.  Either way, man is justified by neither.
