According to Moses, a man with leprosy must conduct himself in a certain way:
As for the leper who has the infection, his clothes shall be torn, and the hair of his head shall be uncovered, and he shall cover his mustache and cry, ‘Unclean! Unclean!’ He shall remain unclean all the days during which he has the infection; he is unclean. He shall live alone; his dwelling shall be outside the camp. (Leviticus 13: 45 – 46)
In the era of Moses, this law makes perfect sense. But in the Messianic Age there is no disease, so it does not make sense to have laws that instruct lepers, who will not exist, how to behave in public. So in the same way that we concluded the laws dealing with death are not eternal, we can conclude the laws dealing with disease are not eternal. There are at least 13 such commands:
| Command | Reference |
|---|---|
| Ritually unclean persons must be kept out of the Temple | Numbers 5: 2 |
| Cattle to be sacrificed must be without blemish | Leviticus 22: 21 |
| A man who has a seminal issue must bring a sacrifice | Leviticus 15: 13 – 15 |
| A woman who has a seminal issue must bring a sacrifice | Leviticus 15: 28 – 29 |
| A leper must bring a sacrifice after he/she has been cleansed. | Leviticus 14: 10 |
| A leper is ritually unclean | Leviticus 13: 3 |
| A leprous garment is ritually unclean | Leviticus 13: 51 |
| A leprous house is ritually unclean | Leviticus 14: 44 |
| A man having a running issue is unclean | Leviticus 15: 2 |
| A woman suffering from running issue is impure | Leviticus 15: 19 |
| To become cleansed of leprosy one must follow the specified procedure | Leviticus 14: 2 |
| To become cleansed of leprosy one must shave off all of one’s hair | Leviticus 14: 9 |
| Until cleansed the leper must be bareheaded with clothing in disarray so as to be easily distinguisable | Leviticus 13: 45 |
These 13 commands, when added to the 15 previously identified commands dealing with death, bring the total of finite positive commands to 28, which equates to 11% of the positive commands of Moses.
