As far as the cubes. I have a little cube of glass given to me by a dear Israeli friend which has carved into it two men holding a pole with a single cluster of grapes on it. I'm sure you know what that means. But the way it is done is interesting. You can only see this scene from without, not within. It is like a prism when the light hits it as well. It makes me wonder if they weren't something like that.
The cube is an interesting geometrical form it has three dimensions, six sides. Three multipled by Six = Eighteen. This is the traditional number in Judaism for life. When viewed on while on one of the corners, triangles appear. If you take it apart, but still keeping it together, you will have four squares bisected by three, forming a cross, or 'T'. This is only one of eleven 'nets' meaning a way that a cube (think of it formed by paper) can be cut where all six sides remain touching, but form a different shape.
It gets much more complicated the more you study on the cube, but what I found interesting is that it says Tablets, plural.
The First Set is described in Exodus,, Thus:
The Second set is described in Deuteronomy as :
It is interesting to note that it says they were written on both their sides. The Hebrew word for 'both' can also mean, not just two, but twelve.
A cube has six sides, but two cubes would have twelve.
But it also says Moses carried these two in his hand, not hand
s. (Which would allow him a hand free for a walking stick).
Now think about this. The dual of a cube is an octahedron. This is a cube (with six sides) within a cube with six sides.
Could this be translated to say:
This would fit with the scene in Revelation where there are twelve thrones, pillars, foundations stones, tribes etc. Also there were the twelve stone on the ephod, twelve cakes put upon the table of shewbread.
Could the 'tablets' look something like this?
