'Patch' in the Bible

The priest will examine him. If there is a white swelling on the skin that has turned the hair white, and there is a patch of raw flesh in the swelling,

“When there is a burn on the skin of one’s body produced by fire, and the patch made raw by the burn becomes reddish-white or white,

when the priest examines it and finds that there is a light or dull white patch of skin on the body, it's a harmless skin eruption that has spread on the skin. The person is clean."
