Leviticus 13:11 Meaning and Commentary

Leviticus 13:11

It [is] an old leprosy in the skin of his flesh
An inveterate one, of long standing and continuance, an obstinate one, not to be cured by medicine; as this sort of leprosy was, and therefore the person was sent not to a physician, but to the priest: the leprosy of sin is an old disease, brought by man into the world with him, and continues with him from his youth upwards, and nothing but the grace of God and blood of Christ can remove it:

and the priest shall pronounce him unclean, and shall not shut him up;
there being no doubt at all of it being a leprosy, and of his uncleanness, and therefore no need to shut him up for further examination, but to turn him out of the camp till his purification was over:

for he [is] unclean;
in a ceremonial sense, and was obliged to the law for cleansing, such as after given.

Leviticus 13:11 In-Context

9 “Anyone who develops a serious skin disease must go to the priest for an examination.

10 If the priest finds a white swelling on the skin, and some hair on the spot has turned white, and there is an open sore in the affected area,

11 it is a chronic skin disease, and the priest must pronounce the person ceremonially unclean. In such cases the person need not be quarantined, for it is obvious that the skin is defiled by the disease.

12 “Now suppose the disease has spread all over the person’s skin, covering the body from head to foot.

13 When the priest examines the infected person and finds that the disease covers the entire body, he will pronounce the person ceremonially clean. Since the skin has turned completely white, the person is clean.
