Sorry Coach, I'm just not seeing the connection on this one. I understand where you want it to go with the wheat heads = white squares and the chaff = black squares on the mosaic pavement and Masons winnowing what is important from what is not. (i.e. an EA divesting themselves of superfluities) I just don't know that I agree with your symbolism on this one.
Mount Moriah was used for winnowing until it was purchased by David where he built an altar for sacrifice. It wasn't until his son Solomon built The Temple that the mosaic pavement comes in. My point is, once the land was purchased it ceased to be used for the purpose of winnowing and became a place dedicated to sacrifice and offerings to G-d. And most every lecture focuses on the mosaic pavement as a representation of the good and bad in persons life making a whole. It is no coincidence that our altars in our Lodges are placed at the center of these mosaic pavements. Don't get me wrong, there are arguments to be made about sacrifice and divesting.
We already, though, have a working tool in Masonic symbolism that has the symbolic use of divesting ourselves from superfluities, or unnecessary aspects that are distractions, or keep us from positive growth. Basically winnowing.
I am not dismissing your connections out of hand, I just feel there are many more important lessons that can be gleaned from the acquisition of Mount Moriah by David than this one. For instance, a sacrifice that costs one nothing is worthless, and a place of worship acquired unfairly diminishes it.
