A leper. — The discussion of leprosy, as to its nature, symptoms, and causes, would be at once long and difficult. The word, which is Greek and not Hebrew in its origin, has probably been used with varying extent of meaning, sometimes including elephantiasis, or even cancer. Even in its narrower meaning, as used by Hippocrates, leprosy was subdivided into three kinds: (1) the mealy, (2) the white, (3) the black, according to the appearance presented by the portions of diseased flesh. Confining ourselves to the Biblical form of the disease, we note (1) its probable origin in the squalor and wretchedness of the Egyptian bondage. It was the “botch,” or plague “of Egypt” (Deuteronomy 28:27). In the Egyptian legends of the Exodus, indeed, the Israelites were said to have been expelled because they were lepers. (2) Its main features were the appearance of a bright spot on the flesh, whiter than the rest, spreading, in flaming, cracking; an ichorous humour oozing from the cracks, the skin becoming hard, scaly, “as white as snow” (Exodus 4:6; 2 Kings 5:27). One so affected was regarded as unclean; his touch brought defilement (Leviticus 13:3; Leviticus 13:11; Leviticus 13:15). He was looked upon as smitten with a divine plague, and cases like those of Miriam and Gehazi gave strength to the belief. He had to live apart from his fellows, to wear on his brow the outward sign of separation, to cry out the words of warning, “Unclean, unclean” (Leviticus 13:45). The idea which lay at the bottom of this separation seems to have been one of abhorrence rather than precaution. The disease was loathsome, but there is no evidence that it was contagious, or even believed to be contagious. At the stage in which it reached its height, and the whole body was covered with the botch and scabs, the man was, by a strange contrast, declared to be ceremonially clean (Leviticus 13:13), and in this state, therefore, the leper might return to his kindred, and take his place among the worshippers of the synagogue. In the case now before us, the man would appear to have been as yet in the intermediate stage. St. Luke describes him, however, as “full of leprosy.”
Worshipped him — i.e., as in St. Mark, “falling on his knees,” or in St. Luke, “falling on his face,” in the highest form of Eastern homage. The act gave to the word “Lord” the emphasis of one, at least, of its higher meanings.
If thou wilt, thou canst make me clean. — The words imply either that he had seen or heard of our Lord’s works of healing, or that His words had impressed him with the belief that the Teacher must have a power extending to acts also. There does not appear to have been any previous case of leprosy miraculously cleansed. The words of the man involve a singular mingling of faith and distrust. He believes in the power, he does not as yet believe in the will. Can it stoop to one so foul as he? If he shared the common feeling that leprosy was the punishment of sin, he might ask: himself, Will He pity and relieve one so sinful?
