On one occasion Jesus was staying in a town, when he saw a man who was covered with leprosy. When the leper saw Jesus, he threw himself on his face and implored his help: "Master, if only you are willing, you are able to make me clean."
And then Jesus impressed upon him that he was not to say a word to any one, "but," he added, "set out and show yourself to the priest, and make the offerings for your cleansing, in the manner directed by Moses, as evidence of your cure."
