TSK · Leviticus 13:1

Take heed in the plague of leprosy, that thou observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so ye shall observe to do.

And it came to pass, while he was in one of the cities, behold, a man full of leprosy: and when he saw Jesus, he fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean.
