Leviticus 13:11

11 it shall be deemed the eldest leprosy, and grown to the skin; therefore the priest shall defoul him, that is, deem him to be foul, and the priest shall not close him again, for it is of open uncleanness. (it shall be judged to be an old leprosy, or a chronic skin disease, grown in the skin; and so the priest shall pronounce him to be defiled, or unclean, but he shall not enclose him again, for it is an open uncleanness.)

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 If the wound of leprosy is in a man [If the plague of leprosy is in a man], he shall be brought to the priest,

10 and he shall see the man; and when white colour is in the flesh, and it changeth the sight, or former colour, of [the] hairs, and that flesh appeareth quick, or waxing (and that flesh appeareth to be raw),

11 it shall be deemed the eldest leprosy, and grown to the skin; therefore the priest shall defoul him, that is, deem him to be foul, and the priest shall not close him again, for it is of open uncleanness. (it shall be judged to be an old leprosy, or a chronic skin disease, grown in the skin; and so the priest shall pronounce him to be defiled, or unclean, but he shall not enclose him again, for it is an open uncleanness.)

12 But if the leprosy running about in the skin flowereth out, (or spreadeth,) and covereth all the flesh, from the head till to the feet, (on) whatever thing falleth under the sight of (his) eyes;

13 the priest shall behold him, and he shall deem him to be holden with the cleanest leprosy, for all the skin is turned into whiteness, and therefore the man shall be clean. (the priest shall examine him, and he shall pronounce him to be clean, for all the skin hath turned white, and so the man shall be clean.)
