Rashi
Arrange to cure him of this tzora’as. ‘אֲסֵפָה’ [=gathering], pertaining to a metzora, is an expression of his cure, because when he is cured, he is [once again] gathered in among people, but during his illness, everyone stays away from him.4The Torah forbids a metzora to dwell within the camp of Yisroel. See Vayikra 13:46. However, even among the other nations a metzora is excluded from the general community until he is cured.
