Matthew 8:2

There came a leper - No disease with which the human family has been afflicted has been more dreadful than that which is often mentioned in the Bible “as the leprosy.” It first exhibits itself on the surface of the skin. The appearance is not always the same, but it commonly resembles the spot made by the puncture of a pin or the pustules of a ringworm. The spots generally make their appearance very suddenly. Perhaps its appearance might be hastened by any sudden passion, as fear or anger. See Num 12:10; 2 Chronicles 26:19. The spots commonly exhibit themselves at first on the face, about the nose and eyes, and increase in size a number of years, until they become as large as a pea or a bean.

There are three kinds of leprosy, distinguished by the appearance of the spots - the white, the black, and the red leprosy. These spots, though few at first, gradually spread until they cover the whole body.

But, though the “appearance” of the disease is at first in the skin, yet it is deeply seated in the bones, and marrow, and joints of the body. We have reason to suppose that in children it is concealed in the system for a number of years until they arrive at the age of puberty; and in adults for three or four years, until at last it gives fearful indications on the skin of its having gained a well-rooted and permanent existence. A leprous person may live twenty, or thirty, or even fifty years, if he received the disease at his birth, but they will be years of indescribable misery. The bones and marrow are pervaded with the disease. The malady advances from one stage to another with slow and certain ruin. “Life still lingers amid the desolation;” the joints, and hands, and feet lose their power; and the body “collapses,” or falls together in a form hideous and awful. There is a form of the disease in which it commences at the extremities: the joints separate; the fingers, toes, and other members one by one fall off; and the malady thus gradually approaches the seat of life. The wretched victim is thus doomed to see himself dying “piecemeal,” assured that no human power can arrest for a moment the silent and steady march of this foe to the seat of life.

This disease is contagious and hereditary. It is easily communicated from one to another, and is transmitted to the third and fourth generation. The last generation that is afflicted with it commonly exhibits the symptoms by decayed teeth, by a fetid breath, and by a diseased complexion.

Moses gave particular directions by which the real leprosy was to be distinguished from other diseases. See Leviticus 13. The leprous person was, in order to avoid contagion, very properly separated from the congregation. The inspection of the disease was committed to the priest; and a declaration on his part that the person was healed, was sufficient evidence to restore the afflicted man to the congregation. It was required, also, that the leprous person should bring an offering to the priest of two birds, probably “sparrows” (see Leviticus 14:4 ‘s margin), one of which was slain and the other dismissed, Leviticus 14:5. In compliance with the laws of the land, Jesus directed the man that he had healed to make the customary offering, and to obtain the testimony of the priest that he was healed. The leprosy has once, and but once, appeared in America. This loathsome and most painful disease has in all other instances been confined to the Old World, and chiefly to the Eastern nations.

It is matter of profound gratitude to a benignant God that this scourge has been permitted but once to visit the New World. That awful calamity was on the island of Guadeloupe, in the West Indies, about the year 1730, and is thus described by an eye-witness: “Its commencement is imperceptible. There appear only some few white spots on the skin. At first they are attended with no pain or inconvenience, but no means whatever will remove them. The disease imperceptibly increases for many years. The spots become larger, and spread over the whole body. When the disease advances, the upper part of the nose swells, the nostrils become enlarged, and the nose itself grows soft. Tumors appear on the jaws; the eyebrows swell; the ears become thick; the points of the fingers, as also the feet and the toes, swell; the nails become scaly; the joints of the hands and feet separate and drop off. In the last stage of the disease the patient becomes a hideous spectacle, and falls to pieces.

Worshipped him - Bowed down before him, to show him respect. See the notes at Matthew 2:2.

If thou wilt - This was an exhibition of great faith, and also an acknowledgment of his dependence on the will of Jesus, in order to be healed. So every sinner must come. He must feel that Jesus “can” save him. He must also feel that he has no claim on him; that it depends on his sovereign will; and must cast himself at his feet with the feelings of the leper:

“I can but perish if I go;

I am resolved to try;

For if I stay away, I know

I shall forever die.”

Happily, no one ever came to Jesus with this feeling who was not received and pardoned.

Make me clean - Heal me. The leprosy was regarded as an unclean and disgusting disease. To be “healed,” therefore, was expressed by being “cleansed” from it.
