'Appearance' in the Bible

The priest is to examine him, and if the swelling of the infection on his bald head or forehead is reddish-white, like the appearance of a skin disease on his body,

After it has been washed, the priest is to reexamine the contamination. If the appearance of the contaminated article has not changed, it is unclean. Even though the contamination has not spread, you must burn up the fabric. It is a fungus on the front or back of the fabric.
