Commentators explain that the cleansing rituals were not merely ceremonial but symbolized the Levites' total dedication to God. By being shaved, sprinkled, and washed, they were acknowledging they were 'no longer their own masters' (Calvin). This act of 'putting off their flesh' (Calvin) signified a radical break from their former lives to become fit to serve in God's holy presence, illustrating the principle that those who serve God must first be wholly consecrated to Him.
