| Barnes' Notes on the Bible And there came a leper ... - See the notes at Matthew 8:1-4. Kneeling down to him - He kneeled and inclined his face to the ground, in token of deep humiliation and earnest entreaty. Compare Luke 5:12. If thou wilt - This was an acknowledgment of the almighty power of Jesus, and an appeal to his benevolence. Make me clean - You (Jesus) can heal me of this loathsome and offensive disease, in the eye of the law justly regarded as "unclean," and render me "legally" clean, and restore me to the privileges of the congregation. And Jesus ...touched him - It was by the law considered as unclean to touch a leprous man. See Numbers 5:2. The fact that Jesus touched him was evidence that the requisite power had been already put forth to heal him; that Jesus regarded him as already clean. I will - Here was a most manifest proof of his divine power. None but God can work a miracle; yet Jesus does it by his "own will" - by an exertion of his own power. Therefore, Jesus is divine. See thou say nothing to any man - The law of Moses required that a man who was healed of the leprosy should be pronounced clean by the priest before he could be admitted again to the privileges of the congregation, Leviticus 14. Christ, though he had cleansed him, yet required him to be obedient to the law of the land - to go at once to the priest, and not to make delay by stopping to converse about his being healed. It was also possible that, if he did not go at once, evil-minded men would go before him and prejudice the priest, and prevent his declaring the healing to be thorough because it was done by Jesus. It was of further importance that "the priest" should pronounce it to be a genuine cure, that there might be no cavils among the Jews against its being a real miracle. Offer for thy cleansing those things ... - Two birds, and cedar-wood, and scarlet, and hyssop; and after eight days, two he-lambs, without blemish, and one ewe-lamb, and fine flour, and oil, Leviticus 14:4, Leviticus 14:10. For a testimony unto them - Not to the priest, but to the people, that they may have evidence that it is a real cure. The testimony of the priest on the subject would be decisive.
Clarke's Commentary on the BibleThere came a leper - See the notes on Matthew 8:2, etc. Should any be inclined to preach on this cleansing of the leper, Mark is the best evangelist to take the account from, because he is more circumstantial than either Matthew or Luke. I. Consider this leper. 1. He heard of Jesus and his miracles. 2. He came to him for a cure, conscious of his disease. 3. He earnestly besought him to grant the mercy he needed. 4. He fell down on his knees, (with his face to the earth, Luke 5:12), thus showing his humbled state, and the distress of his soul. 5. He appealed to his love - if thou wilt; with a full conviction of his ability - thou canst; in order to get healed. II. Consider Jesus. 1. He is moved with tender compassion towards him: this is the alone source of all human salvation. 2. He stretches forth his hand, showing thus his readiness to relieve him. 3. He touches him; though this was prohibited by the law, and rendered him who did it in any common case legally unclean. 4. He proves at once his infinite love and unlimited power, by his word and by his act; I will - be thou cleansed; and immediately his leprosy was removed. But see on Matthew 8:2 (note).
Gill's Exposition of the Entire BibleAnd there came a leper to him,.... After he was come down from a certain mountain, in Galilee, where he had been preaching to the people, Matthew 8:1, and when be was in a certain city, Luke 5:12, either Capernaum, or some other city of Galilee. This man was full of leprosy, as Luke says, and very probably deemed incurable; of the nature and symptoms of the leprosy; see Gill on Luke 5:12, beseeching him; to cure him of his leprosy: and kneeling down to him; in token of submission, respect, and reverence, and to worship him: and saying unto him, if thou wilt thou canst make me clean; See Gill on Matthew 8:2. Mark omits the word "Lord".
Geneva Study Bible{12} And there came a leper to him, beseeching him, and kneeling down to him, and saying unto him, If thou wilt, thou canst make me clean. (12) By healing the leprous he shows that he came for this reason: to wipe out the sins of the world with his touch.
People's New Testament 1:40 There came a leper. See notes on Mt 8:2-4. Compare also Lu 5:12-15. This miracle occurred after the Sermon on the Mount. Leprosy, that terrible scourge of the East, is unknown in our times, or even in the United States.

Matthew Henry's Concise Commentary1:40-45 We have here Christ's cleansing of a leper. It teaches us to apply to the Saviour with great humility, and with full submission to his will, saying, Lord, if thou wilt, without any doubt of Christ's readiness to help the distressed. See also what to expect from Christ; that according to our faith it shall be to us. The poor leper said, If thou wilt. Christ readily wills favours to those who readily refer themselves to his will. Christ would have nothing done that looked like seeking praise of the people. But no reasons now exist why we should hesitate to spread the praises of Christ.
Matthew Henry's Whole Bible CommentaryVerses 40-45 We have here the story of Christ's cleansing a leper, which we had before, Mt. 8:2-4. It teaches us, 1. How to apply ourselves to Christ; come as this leper did, (1.) With great humility; this leper came beseeching him, and kneeling down to him (v. 40); whether giving divine honour to him as God, or rather a less degree of respect as a great Prophet, it teaches us that those who would receive grace and mercy from Christ, must ascribe honour and glory to Christ, and approach to him with humility and reverence. (2.) With a firm belief of his power; Thou canst make me clean. Though Christ's outward appearance was but mean, yet he had this faith in his power, which implies his belief that he was sent of God. He believes it with application, not only in general, Thou cast do every thing (as Jn. 11:22), but, Thou cast make me clean. Note, What we believe of the power of Christ we must bring home to our particular case; Thou canst do this for me. (3.) With submission to the will of Christ; Lord, if thou wilt. Not as if he had any doubt of Christ's readiness in general to help the distressed, but, with the modesty that became a poor petitioner, he refers his own particular case to him. 2. What to expect from Christ; that according to our faith it shall be to us. His address is not in the form of prayer, yet Christ answered it as a request. Note, Affectionate professions of faith in Christ, and resignations to him, are the most prevailing petitions for mercy from him, and shall speed accordingly. (1.) Christ was moved with compassion. This is added here, in Mark, to show that Christ's power is employed by his pity for the relief of poor souls; that his reasons are fetched from within himself, and we have nothing in us to recommend us to his favour, but our misery makes us the objects of his mercy. And what he does for us he does with all possible tenderness. (2.) He put forth his hand, and touched him. He exerted his power, and directed it to this creature. In healing souls, Christ toucheth them, 1 Sa. 10:26. When the queen toucheth for the evil, she saith, I touch, God heals; but Christ toucheth and healeth too. (3.) He said, I will, be thou clean. Christ's power was put forth in and by a word, to signify in what way Christ would ordinarily work spiritual cures; He sends his word and heals, Ps. 107:20; Jn. 15:3; 17:17. The poor leper put an if upon the will of Christ; If thou wilt; but that doubt is soon put out of doubt; I will. Christ most readily wills favours to those that most readily refer themselves to his will. He was confident of Christ's power; Thou canst make me clean; and Christ will show how much his power is drawn out into act by the faith of his people, and therefore speaks the word as one having authority, Be thou clean. And power accompanied this word, and the cure was perfect in an instant; Immediately his leprosy vanished, and there remained no more sign of it, v. 42. 3. What to do when we have received mercy from Christ. We must with his favours receive his commands. When Christ had cured him, he strictly charged him; the word here is very significant, embrimeµsamenos-graviter interminatus-prohibiting with threats. I am apt to think that this refers not to the directions he gave him to conceal it (v. 44), for those are mentioned by themselves; but that this was such a charge as he gave to the impotent man whom he cured, Jn. 5:14, Sin no more, lest a worse thing come unto thee; for the leprosy was ordinarily the punishment of some particular sinners, as in Miriam's, Gehazi's, and Uzziah's, case; now, when Christ healed him, he warned him, he threatened him with the fatal consequence of it if he should return to sin again. He also appointed him, (1.) To show himself to the priest, that the priest by his own judgment of this leper might be a witness for Christ, that he was the Messiah, Mt. 11:5. (2.) Till he had done that, not to say any thing of it to any man: this is an instance of the humility of Christ and his self-denial, that he did not seek his own honour, did not strive or cry, Is. 42:2. And it is an example to us, not to seek our own glory, Prov. 25:27. He must not proclaim it, because that would much increase the crowd that followed Christ, which he thought was too great already; not as if he were unwilling to do good to all, to as many as came; but he would do it with as little noise as might be, would have no offence given to the government, no disturbance of the public peace, not any thing done that looked like ostentation, or an affecting of popular applause. What to think of the leper's publishing it, and blazing it abroad, I know not; the concealment of the good characters and good works of good men better become them than their friends; nor are we always bound by the modest commands of humble men. The leper ought to have observed his orders; yet, no doubt, it was with a good design that he proclaimed the cure, and it had no other ill effect than that it increased the multitudes which followed Christ, to that degree, that he could no more openly enter into the city; not upon the account of persecution (there was no danger of that yet,) but because the crowd was so great, that the streets would not hold them, which obliged him to go into desert places, to a mountain (ch. 3:13), to the sea-side, ch. 4:1. This shows how expedient it was for us, that Christ should go away, and send the Comforter, for his bodily presence could be but in one place at a time; and those that came to him from every quarter, could not get near him; but by his spiritual presence he is with his people wherever they are, and comes to them to every quarter. |
