'Spots' in the Bible

'And when a man or woman hath in the skin of their flesh bright spots, white bright spots,

and the priest hath seen, and lo, in the skin of their flesh white weak bright spots, it is a freckled spot broken out in the skin; he is clean.

Doth a Cushite change his skin? and a leopard his spots? Ye also are able to do good, who are accustomed to do evil.
