Of all the curious laws of tzaraas, one stands out in particular. A person whose skin is entirely bleached white from the illness is not impure, and is not quarantined from the camp.
R’ Shlomo Farhi explains that it is simply impossible for a Jew to be so absolutely in the wrong that he must be forced to leave.
Yet when such a person begins to heal slightly, they become impure under the regular laws of tzaraas.
This seems counter intuitive. Why does recovery make him worse off?
Rabbi Farhi teaches that so long as a person is completely covered, he’s well aware that there’s plenty to fix. When you hit rock bottom, the only way is up. Once there’s something else to hold on to, he can righteously cling to the little bit of goodness, but doing so will ultimately prevent him from acknowledging the need to improve in other areas.
In order to get better, it is essential to recognize our shortcomings.
