When the priest enters the Holiest place on Yom Kippur, he is boxed in between the Ark, the Veil, and the two poles of the Ark. God doesn't allow him a lot of leeway in conducting the day's services.

In a way, the Ark and its covering are a model of the priesthood, whether that of Melchizedek, Aaronic, family, or believer. A priest covers his people and enables them to approach God.
