(40-43) And there came a leper.--See Notes on Matthew 8:1-4. The miracle appears in St. Matthew as following closely on the Sermon on the Mount.

Verse 40. - The healing of the leper is recorded in all the three synoptic Gospels; but St. Mark gives more full details. From St. Matthew we learn that it took place after the sermon on the mount; and yet not at the very close of his missionary circuit, St. Luke (Luke 5:12) says that the diseased man was "full of leprosy" (πλήρης λέπρας). The disorder was fully developed; it had spread over his whole body; he was leprous from head to foot. This leprosy was designed to be specially typical of the disease of sin. It was not infectious. It was not because it was either infectious or contagious that the leper was bidden under the Jewish Law to wars others off, in the words," Unclean! un-clean!" It was in some cases hereditary. It was a very revolting disease. It was a poisoning of the springs of life. It was a living death. It was incurable by any human art or skill. It was the awful sign of sin reaching unto death; and it was cured, as sin is cured, only by the mercy and favor of God. No wonder, then, that our Lord specially displayed his power over this terrible disease, that he might thus prove his power over the still worse malady of sin. St. Mark here tells us that this leper knelt down (καὶ γονυπετῶν). St. Matthew says (Matthew 8:2) that he "worshipped him," (προσεκύνει αὐτῷ); St. Luke says (Luke 5:12) that "he fell on his face" (πεσὼν ἐπὶ πρόσωπον). We thus see that the scriptural idea of worship is associated with some lowly posture of the body. But with this worship of the body, the leper offered also the homage of the soul. His prostration of himself before Christ was not merely a rendering of honor to an earthly being; it was a rendering of reverence to a Divine Being. For he does not say to him, "If thou wilt ask of God, he will give it thee;" but he says, "If thou wilt, thou canst make me clean." It is as though he said, "I know that thou art of equal power with the Father, and therefore supreme Lord over diseases; so that by thy word alone thou canst remove this leprosy from me. I ask, therefore, that thou wouldst be willing to do this, and then I know that the thing is done." The leper had faith in the Divine power of Christ, partly out of his own inward illumination, and partly by the evidence of the miracles which Christ had already wrought. If thou wilt, thou east. Observe the hypothetic expression, "If thou wilt." He has no doubt as to Christ's power, but the words, "If thou wilt" show that his desire for healing was controlled by resignation to the will of God. For bodily diseases are often necessary for the health of the soul; and this God knows, though man knows it not. Therefore, in asking for earthly blessings, it behoves us to resign ourselves to the will and wisdom of God.

1:40-45 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.And 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".
