The priest shall go forth out of the camp - As the leper was separated from the people, and obliged, because of his uncleanness, to dwell without the camp, and could not be admitted till the priest had declared that he was clean; hence it was necessary that the priest should go out and inspect him, and, if healed, offer for him the sacrifices required, in order to his re-admission to the camp. As the priest alone had authority to declare a person clean or unclean, it was necessary that the healed person should show himself to the priest, that he might make a declaration that he was clean and fit for civil and religious society, without which, in no case, could he be admitted; hence, when Christ cleansed the lepers, Matthew 8:2-4, he commanded them to go and show themselves to the priest, etc.

And the priest shall go forth out of the camp,.... A little without the camp, as Ben Gersom notes. There have been several goings forth of Christ our High Priest; first in the council and covenant of grace and peace, when he became the surety of his people; then in time by the assumption of human nature, when he came forth from his Father, and came into the world to save them; next, when he went forth out of the city of Jerusalem to suffer for them; and also, when, at the time of conversion, he goes forth in quest of them, and looks them up, and finds them, and brings them home, which may answer to the type here; and all shows the great readiness of Christ to receive sinners:

and the priest shall look, and, behold, if the plague of leprosy be healed in the leper; that all the signs of uncleanness are removed, the swelling, the scab, or bright spot, and the white hair in them, and, instead of that, black hair is grown up. The typical priest did not heal, nor could he, the healing was of God; he only looked to see by signs if the plague was healed; but our antitypical priest looks with an eye of pity and compassion on leprous sinners, and they are enabled to look to him by faith, and virtue goes out of him to the healing of their diseases; as he looks upon them in their blood, and says to them, Live, so he looks upon them in their leprosy, and touches them, and says, "I will, be thou clean", Matthew 8:3, and they are immediately healed; he is the sun of righteousness, which arises upon them with healing in his wings.

And the priest shall go forth out of the camp; and the priest shall look, and, behold, if the plague of leprosy be healed in the leper;

14:3 Healed by God - For God alone did heal or cleanse him really, the priest only declaratively.

As a type of Gospel salvation the points are:

(1) The leper does nothing Rom 4:5,5.

(2) the priest seeks the leper, not the leper the priest Lk 19:10.

(3) "with-out shedding of blood is no remission" Heb 9:22.

(4) "and if Christ be not raised, your faith is vain" 1Cor 15:17.

14:1-9 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 represent 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. And also that when God by his grace has brought to repentance, they ought with tenderness and joy, and sincere affection, to be received again. Care should always be taken that sinners may not be encouraged, nor penitents discouraged. If it were found that the leprosy was healed, the priest must declare it with the particular solemnities here described. The two birds, one killed, and the other dipped in the blood of the bird that was killed, and then let loose, may signify Christ shedding his blood for sinners, and rising and ascending into heaven. The priest having pronounced the leper clean from the disease, he must make himself clean from all remains of it. Thus those who have comfort of the remission of their sins, must with care and caution cleanse themselves from sins; for every one that has this hope in him, will be concerned to purify himself.
