'Chin' in the Bible

“When a man or woman has an infection on the head or chin,

the priest must examine the infection. If it appears to be deeper than the skin, and the hair in it is yellow and sparse, the priest must pronounce the person unclean. It is a scaly outbreak, a skin disease of the head or chin.

On the seventh day, he is to shave the hair on his head, chin, back, and eyebrows. After he has shaved all his hair, washed his clothes, and bathed himself with water, then he will be clean."

The ends of the hair round your face and on your chin may not be cut off.
