1
The LORD spoke to Moses and Aaron:
2
“When a swelling or a rash or a bright spot appears on the skin of a person’s body, and it may become a leprous disease on his skin, he shall be brought to Aaron the priest, or to one of his sons the priests.
3
The priest shall examine the disease on the skin, and if the hair in the affected place has turned white, and the disease appears to be deeper than the skin, it is a leprous disease; when the priest sees it, he shall declare the person unclean.
4
But if the bright spot on his skin is only white and does not appear to be deeper than the skin, and its hair has not turned white, the priest shall isolate the person for seven days.
5
On the seventh day the priest shall examine him; and if in his judgment the disease remains unchanged and has not spread on the skin, the priest shall isolate him for seven more days.
6
Then on the seventh day the priest shall examine him again; if the disease has faded and has not spread on the skin, the priest shall declare him clean; it is only a rash. He shall wash his clothes, and he will be clean.
7
But if the rash does spread on the skin after he has been examined by the priest for cleansing, then he shall be examined again.
8
If, after the priest’s examination, the rash has spread on the skin, the priest shall declare him unclean; it is leprosy.
9
When a person has leprosy, he shall be brought to the priest.
10
If the priest examines him and there is a white swelling on the skin that has turned the hair white, and raw flesh appears in the swelling,
11
it is a chronic leprosy on his skin. The priest shall declare him unclean; he need not isolate him, because he is already unclean.
12
If leprosy breaks out all over the skin, so that it covers the whole skin of the afflicted person, from head to foot, as far as the priest can see,
13
and if, on examination, the leprosy has covered the whole body, the priest shall declare him clean; he has turned entirely white, and so he is clean.
14
But whenever raw flesh appears in him, he is unclean.
15
When the priest sees the raw flesh, he shall declare the person unclean; the raw flesh is unclean, and it is leprosy.
16
Or if the raw flesh changes and turns white again, then the person shall come to the priest.
17
If, on examination, the disease has turned white, the priest shall declare the person clean; he is clean indeed.
18
If on a person’s skin there is a boil that has healed,
19
but in the place of the boil there appears a white swelling or a reddish-white spot, that person shall be brought to the priest for examination.
20
If, in his examination, the spot appears deeper than the skin and its hair has turned white, then the priest shall declare the person unclean, for it is a leprous disease that has broken out in the boil.
21
But if the priest examines the spot and finds that there is no white hair in it, and that it is not deeper than the skin, but has faded, the priest shall isolate that person for seven days.
22
And if the spot does spread on the skin, the priest shall declare him unclean; it is leprosy.
23
But if the spot remains as it is and does not spread, then it is the scar of the boil, and the priest shall declare the person clean.
24
Or if on a person’s skin there is a burn from fire, and the raw flesh that appears in the burn becomes a reddish-white or white spot,
25
then the priest shall examine the spot; if the hair in the spot has turned white and the spot appears deeper than the skin, then what has broken out in the burn is leprosy, and the priest shall declare the person unclean; it is leprosy.
26
But if, in his examination, there is no white hair in the spot and the spot is not deeper than the skin, but has faded, the priest shall isolate that person for seven days.
27
On the seventh day the priest shall examine him again; if the spot has indeed spread on the skin, then the priest shall declare him unclean; it is leprosy.
28
But if the spot remains as it is and does not spread on the skin, but has faded, then it is the swelling from the burn, and the priest shall declare him clean, for it is the scar of the burn.
29
When a man or a woman has a disease on the head or in the beard,
30
the priest shall examine the disease; if it appears deeper than the skin, and there is in it thin yellow hair, then the priest shall declare the person unclean, for it is a scaly disease of the head, that is, leprosy of the head or leprosy of the beard.
31
And if, in his examination, the scaly disease does not appear deeper than the skin and there is no black hair in it, then the priest shall isolate the person afflicted with the scaly disease for seven days.
32
On the seventh day the priest shall examine the disease; if it is found that the scaly disease has not spread and there is no yellow hair in it, and the scaly disease does not appear deeper than the skin,
33
then the person shall shave himself, but the place of the scaly disease he shall not shave. Then the priest shall isolate the person with the scaly disease a second time for seven more days.
34
Then on the seventh day the priest shall examine the mark again; and if the mark has not spread on the skin, and does not appear to be deeper than the skin, then the priest shall declare him clean, and he shall wash his clothes and be clean.
35
But if the mark does spread on the skin after he has been declared clean,
36
and the priest, upon examination, finds that the mark has spread on the skin, then the priest need not look for the yellow hair; the man is unclean.
37
But if, in the priest’s sight, the mark remains as it was, and black hair has grown in the mark, then the mark has been healed, and the man is clean; and the priest shall declare him clean.
38
When a man or a woman has white spots on the skin, that is, white spots,
39
the priest shall examine them; and if the spots on the skin are dull white, it is only a rash that has broken out on the skin, and the person is clean.
40
If a man’s hair falls out from his head, and he becomes bald, he is clean.
41
If his hair falls out from the front of his head, and he becomes bald in front, he is clean.
42
But if on the bald head, on the top or on the front, there is a reddish-white disease, it is a leprous disease breaking out on the bald part of the head.
43
Then the priest shall examine him; and if it appears that the swelling on the bald part of the head is reddish-white, and looks like leprosy on the skin,
44
then the man is a leper, and he is unclean; and the priest shall declare him unclean because of the disease on his head.
45
The leper shall wear torn clothes, let his hair hang loose, and cover his face, crying out, Unclean! Unclean!
46
As long as he has the disease, he remains unclean; he is indeed unclean. He shall live apart; outside the camp shall be his dwelling.
47
If there is a leprous mark in a garment, in a wool garment or a linen garment,
48
whether in the warp or in the weft, whether in leather or in any article of leather,
49
— if the mark in those things is reddish in color, it is leprosy — it shall be shown to the priest.
50
When the priest has examined the mark, he shall isolate the one who has the mark for seven days.
51
On the seventh day he shall examine the mark again; and if the mark has spread in the garment, or in the warp or in the weft, or in the leather, whatever use the leather may be put to, it is a very harmful leprosy, and the article is unclean.
52
He shall burn the articles that have the mark, for it is a malignant leprosy; the articles shall be burned up completely.
53
But if, in the priest’s examination, the mark has not spread on the articles,
54
then the priest shall order the article with the mark to be washed, and he shall isolate it for seven more days a second time.
55
Then after the article has been washed, the priest shall examine the mark again; and if it appears that the appearance of the mark has not changed, even though it has not spread, then the article is unclean, and you shall burn it up completely, because the mark has eaten into it on the back side or on the front side.
56
And if, in the priest’s examination, the mark has faded after it was washed, then he shall tear it out of the articles.
57
But if the mark appears again on the articles, it is a leprosy breaking out; the article that has the mark shall be burned up completely.
58
But the articles that you have washed, so that the mark has disappeared from them, shall be washed a second time; then they shall be clean.
59
This is the law concerning leprosy in a woolen garment or a linen garment, or in the warp or the weft, or in any article of leather, for declaring it clean or unclean.”
⚠️🧑⚕️🩺 Summary of Leviticus 13 – The Priest’s Examination of Leprosy
Leviticus 13 is the first of two chapters dealing with leprosy and skin uncleanness. Leprosy here is not only the disease as we know it today, but a general term for various kinds of skin disorders. The priest served as a “spiritual examiner” to determine whether a person was unclean or clean based on physical signs.
1. Symptoms on the Skin (verses 1–17)
- If there is a swelling, rash, or white spot on the skin, the person must come to the priest.
- The priest will examine and may:
Declare unclean (leprosy)
Quarantine for 7 days and examine again
Declare clean if the symptoms heal
🔁 The examination may be repeated for several days to confirm the status.
2. Old Leprosy That Spreads (verses 18–28)
- If an old sore (for example from a boil or a burn) develops into a white patch or peeling, that too may be a sign of leprosy.
- The priest evaluates according to the size, depth of the wound, and the color of the hair in the wound.
🧑⚕️ The priest is not a doctor, but a spiritual assessor who declares whether a person is unclean or not.
3. Disease on the Head or Beard (verses 29–44)
- If leprosy appears on the head/beard → the hair turns white and the sore looks deep → unclean.
- That person must:
Cover his mouth
Live apart outside the camp
Cry out: “Unclean! Unclean!” if others come near
😷 This reflects social and spiritual isolation because of sin.
4. Leprosy on Clothing (verses 47–59)
- Leprosy can also appear on wool, linen, leather, or mixed-fabric clothing.
- If there are greenish or reddish spots, the clothing must be quarantined.
- If the stain spreads → burned. If not → it can be washed and worn again if it is healed.
👕 A symbol that uncleanness can spread to inanimate things and needs to be dealt with.
📖 Main Teaching
- The Lord cares about the health and holiness of His people—outside and within.
- Sin often begins with a small sign—but if ignored, it can spread.
- The priest represents God in judging the spiritual and social condition of the people.
- Purification requires time, process, and caution, not quick judgment.
- Uncleanness separates a person from the community and worship.
✨ Spiritual Meaning
- Leprosy in the Bible is a symbol of sin—it may seem small, but it takes root and separates us from God and from one another.
- The priest represents Jesus Christ, our High Priest, who can declare unclean or heal and declare clean.
- The unclean person was told to stay outside the camp—like how sin separates us from fellowship and worship.
- Today, the Lord does not look only at the outward appearance, but at our hearts—whether there is any “spiritual disease” that has not yet been dealt with.
- This law also teaches the importance of a community guarding holiness together.
