This week, we are introduced to what will become the holiest object in the Hebrew Bible, although it is not really so much an object as it is a container. The Ark will occupy the innermost sanctum of the mishkan, the “Holy of Holies,” and it is from above the Ark that God communicates with Moshe (see Exodus 25:22).  The camp of Israel was centered around it at rest, and carried it with them as they marched through the wilderness.  A midrash, however, notices that this Ark, the Aron ha-Edut, was not the only aron the Children of Israel carried with them through the wilderness.
