What does Leviticus 14:17 mean?

The priest will then put some of the oil that's left in his hand on the same places he put the blood—the right earlobe, right thumb, and right big toe of the person being cleansed. Leviticus 14:17 - Modern Text Bible

(The oil is applied to the same spots as the blood, reinforcing the idea of total restoration—spiritually and physically.)
