42 But if he has a reddish-white sore on his bald head or forehead, it is a defiling disease breaking out on his head or forehead.

Read Leviticus 13:42 Using Other Translations

And if there be in the bald head, or bald forehead, a white reddish sore; it is a leprosy sprung up in his bald head, or his bald forehead.
But if there is on the bald head or the bald forehead a reddish-white diseased area, it is a leprous disease breaking out on his bald head or his bald forehead.
However, if a reddish white sore appears on the bald area on top of his head or on his forehead, this is a skin disease.
