Leviticus 7:10
And every meat offering, mingled with oil, and dry, shall all the sons of Aaron have, one as much as another.
Leviticus 13:30
Then the priest shall see the plague: and, behold, if it be in sight deeper than the skin; and there be in it a yellow thin hair; then the priest shall pronounce him unclean: it is a dry scall, even a leprosy upon the head or beard.
