'Examination' in the Bible

The priest will make an examination, and if the spot seems to be beneath the skin and the hair in it has turned white, the priest must pronounce him unclean; it is a skin disease that has broken out in the boil.

the priest is to make an examination. If the spots on the skin of the body are dull white, it is only a rash that has broken out on the skin; the person is clean.
