'Spots' in the Bible

"And when a man or a woman {has} spots on their body's skin, white spots,

then the priest shall examine [them], and {if} [the] spots on their body's skin [are] faded white, it [is] a skin rash; it has broken out on the skin--it [is] clean.

And he shall examine the infection, and {if} the infection on the house's wall [has] yellowish-green or reddish spots and its appearance [is] deeper than [the surface of] the wall,

Can a Cushite change his skin, or a leopard his spots? [Then] you also will be able to do good, [who] are accustomed to doing evil.
