The Purification of Sanctuary Impurities in the Temple

The ultimate source of impurity is human sin. Sin must therefore be expiated. The continual purging and reconsecration of the altar points to the singular function of the altar. It is the medium of God's salvific expiation of the sins of Israel. Therefore, not only does it have to be purged of Israel's sins, it must be a fit instrument for effecting expiation when sacrifices are offered upon it.
