Leviticus 13:2-19

²If a man has on his skin a growth or a mark or a white place, and it becomes the disease of a leper, let him be taken to Aaron the priest, or to one of the priests, his sons;

³And if, when the priest sees the mark on his skin, the hair on the place is turned white and the mark seems to go deeper than the skin, it is the mark of a leper: and the priest, after looking at him, will say that he is unclean.

⁴But if the mark on his skin is white, and does not seem to go deeper than the skin, and the hair on it is not turned white, then the priest will keep him shut up for seven days;

⁵And the priest is to see him on the seventh day; and if, in his opinion, the place on his skin has not become worse and is not increased in size, then the priest will keep him shut up for seven days more:

⁶And the priest is to see him again on the seventh day; and if the mark is less bright and is not increased on his skin, then let the priest say that he is clean: it is only a skin-mark, and after his clothing has been washed he will be clean.

⁷But if the size of the mark on his skin is increased after he has been seen by the priest, let him go to the priest again:

⁸And if, after looking at him, he sees that the mark is increased in his skin, let the priest say that he is unclean; he is a leper.

⁹When the disease of a leper is seen on a man, let him be taken to the priest;

¹⁰And if the priest sees that there is a white growth on the skin, and the hair is turned white, and there is diseased flesh in the growth,

¹¹It is an old disease in the skin of his flesh, and the priest will say that he is unclean; he will not have to be shut up, for he is clearly unclean.

¹²And if the disease comes out all over his skin, from his head to his feet, as far as the priest is able to see,

¹³And if the priest sees that all his flesh is covered with the leper's disease, the priest will say that he is clean: it is all turned white, he is clean.

¹⁴But whenever diseased flesh is seen on him, he will be unclean.

¹⁵And when the priest sees the diseased flesh he will say that he is unclean; the diseased flesh is unclean, he is a leper.

¹⁶Or if the diseased flesh is turned again and changed to white then he is to come to the priest,

¹⁷And the priest will see him: and if the place is turned white, then the priest will say that he is free from the disease.

¹⁸And if a bad place has come out on the skin and is well again,

¹⁹And on the same place there is a white growth of a bright mark, red and white, then let the priest see it;
