I can understand Bill's curiousity about a very technical question...language study can become as addictive as as a puzzle, and sometime our attention grabs onto something exactly like he has raised. I myself am not able to answer when the question is about Hebrew; in Greek I might.
Having said all that, I like where you came out.
The first Reformation (Luther and company) basically said, "We're going to stop doing those things that are prohibited by Scripture." There was a later wave of reformers who said, "We're only going to do those things that are commanded by Scripture."
That last group went too far, because their position assumes that every single thing that God might give us permission to do is spelled out in the Bible. This makes the Bible a book of rules that squeezes the joy out of life, rather than a book of principles for abundant living.
I wouldn't personally go the entire distance with Luther, but I'm with him on this point. Wherever God hasn't said "No," in Christ we have God's "Yes."
