'Yellow' in the Bible

then the priest shall examine the plague; and behold, if its appearance is deeper than the skin, and the hair in it is yellow and thin, then the priest shall pronounce him unclean: it is an itch, it is leprosy of the head or of the beard.

On the seventh day the priest shall examine the plague; and behold, if the itch hasn't spread, and there is no yellow hair in it, and the appearance of the itch isn't deeper than the skin,

then the priest shall examine him; and behold, if the itch has spread in the skin, the priest shall not look for the yellow hair; he is unclean.
