John Gill's Bible Commentary Ver. 1. And the Lord spake unto Moses , etc.] In order to deliver the same to Aaron, who, and the priests his successors, were chiefly to be concerned in the execution of the law given: saying ; as follows.
Matthew Henry Commentary
Verses 1-9 - The priests could not cleanse the lepers; but when the Lord removed the plague, various rules were to be observed in admitting them again to the ordinances of God, and the society of his people. They represen many duties and exercises of truly repenting sinners, and the duties of ministers respecting them. If we apply this to the spiritual leprosy of sin, it intimates that when we withdraw from those who walk disorderly we must not count them as enemies, but admonish them as brethren. An also that when God by his grace has brought to repentance, they ough with tenderness and joy, and sincere affection, to be received again Care should always be taken that sinners may not be encouraged, no penitents discouraged. If it were found that the leprosy was healed the priest must declare it with the particular solemnities her described. The two birds, one killed, and the other dipped in the bloo of the bird that was killed, and then let loose, may signify Chris shedding his blood for sinners, and rising and ascending into heaven The priest having pronounced the leper clean from the disease, he mus make himself clean from all remains of it. Thus those who have comfor of the remission of their sins, must with care and caution cleans themselves from sins; for every one that has this hope in him, will be concerned to purify himself.
