I'm not so sure I like that implication, or that it fits with the rest of what I believe. And besides, Scripture doesn't say that the Lord took the Lord from Adam to make Eve.
And this, of course, brings up my favorite fruit - cherries!
When "playing" with gematria, we make these kinds of cherry picking choices all the time. If all we had were lists of words and numbers it wouldn't be worth much. But in my experience, I noticed that the numbers link up with archetypal ideas to form "numerical categories" that cohered with how those numbers and archetypes appear in Scripture and Reality. For example, the category subsumed by the Number 2 includes such concepts as Division, Duality, Image, Reflection and so forth. Thus we find things marked by the Number 2 in Scripture to be based on these concepts:
Second Day - Division of the Waters
Second Book - Divisoion of the Red Sea
Second Commandment - No grave Images
Second Seal - Great Sword (Instrument of Division)
Second Person of the Trinity - The Son (Bet KeyWord Ben) who is the Image of God
And the Son is called the Word and linguists understand the concept of the Word as based fundamentally upon the duality of signifier/signified. And so the Word is sharper than any two-edge sword, dividing between soul and spirit. Etc. and so on and so forth. It is this kind of categorical thinking that I found both valid and valuable. But subtracting Eve from Adam to find the Lord? Not so much.
Now don't get me wong, my friend. I'm not trying to bust your chops. I'm just letting you know how I see things. So don't let my less than enthusiastic response dampen your enthusiam.
