13:45 And the leper in whom the plague [is], his clothes shall be {m} rent, and his head bare, and he shall put a covering upon his upper {n} lip, and shall cry, Unclean, unclean.
(m) In sign of sorrow and lamentation.
(n) Either in token of mourning, or for fear of infecting others.
13:45 His clothes shall be rent - In the upper and fore parts, which were most visible. This was done partly as a token of sorrow, because though this was not a sin, yet it was an effect of sin, and a sore punishment, whereby he was cut off both from converse with men, and from the enjoyment of God in his ordinances; partly as a warning to others to keep at a due distance from him wheresoever he came. And his head bare - Another sign of mourning. God would have men though not overwhelmed with, yet deeply sensible of his judgments. A covering on his upper lip - Partly as another badge of his sorrow and shame, and partly for the preservation of others from his breath or touch. Unclean, unclean - As begging the pity and prayers of others, and confessing his own infirmity, and cautioning those who came near him, to keep at a distance from him.
13:45,46 When the priest had pronounced the leper unclean, it put a stop to his business in the world, cut him off from his friends and relations, and ruined all the comfort he could have in the world. He must humble himself under the mighty hand of God, not insisting upon his cleanness, when the priest had pronounced him unclean, but accepting the punishment. Thus must we take to ourselves the shame that belongs to us, and with broken hearts call ourselves Unclean, unclean; heart unclean, life unclean; unclean by original corruption, unclean by actual transgression; unclean, therefore deserving to be for ever shut out from communion with God, and all hope of happiness in him; unclean, therefore undone, if infinite mercy do not interpose. The leper must warn others to take heed of coming near him. He must then be shut out of the camp, and afterward, when they came to Canaan, be shut out of the city, town, or village where he lived, and dwell with none but those that were lepers like himself. This typified the purity which ought to be in the gospel church.
