LEPROUSY CAN BE HEALED THROUGH REPENTANCE

Midrash Rabbah - Numbers 7:10

‘AND THE CHILDREN OF ISRAEL DID SO, AND PUT THEM OUT WITHOUT THE CAMP (Numbers 5:4): When they sinned they went into exile. AS THE LORD SPORE UNTO MOSES, SO DID THE CHILDREN OF ISRAEL (ib.): What did the Holy One, blessed be He, speak to Moses? That if they would repent while in any of the kingdoms where they might be the Holy One, blessed be He, would gather them together; as it says, And it shall come to pass, when all these things are come upon thee, the blessing and the curse... and shalt return... and hearken to His voice... and the Lord thy God will bring thee into the land... and the Lord thy God will circumcise your heart (Deuteronomy 30:1-6).
