Compare the ear/thumb/toe ritual for the priests in Leviticus 8 to that for the leper in Leviticus 14. Why are they the same?

The leper and priest are both anointed on the ear/thumb/toe with blood. They both sit outside the tent for 7 days.

The leper was separated from the people for sin and must be brought near the people before God. The priest was one of the people, but is now being separated for a special purpose.

The leper was set apart in sin. The priest is now set apart in righteousness.

After the ear/thumb/toe atonement, both priest and leper are enabled to take their place in the community.
