Shemot 25:10. "They
shall make an Ark of acacia wood two and a half amot its
length (about five feet), an amah and a half its width, and an
amah and a half its height."
How do we know that the Aron took up no space?
If you went into the Holy of Holies and measured from one wall
to the Aron in the middle. Then, you measured from the other
side of the Aron to the far wall. That measurement would be the
same as the distance from one wall to the other without taking
the Aron into account. The distance between the two walls of the
Holy of Holies was the same whether you measured from the walls
to the sides of the Aron, or whether you measured the entire width.
The word foundation is apposite. Foundation
connotes both meanings implied here: a) a beginning, a starting
point. And b) the sum total of all that the entity is supposed
to be. For example, the Declaration of Independence was the foundation
of the United States of America. It was both its beginning and
it contained the essence and aspiration of all that the United
States was intended to be.
