'Appearance' in the Bible

And the priest shall look on it, and behold, the rising of the sore is white-reddish in his bald head, or in his bald forehead, like the appearance of the leprosy in the skin of the flesh;

And the priest shall look on the sore after the washing, and behold, if the sore have not changed its appearance, and the sore have not spread, it is unclean: thou shalt burn it with fire: it is a fretting sore on what is threadbare or where the nap is gone.
