'Chin' in the Bible

And when a man or a woman has a disease on the head, or in the hair of the chin,

Then the priest is to see the diseased place: and if it seems to go deeper than the skin, and if there is thin yellow hair in it, then the priest will say that he is unclean: he has the mark of the leper's disease on his head or in the hair of his chin.

And on the seventh day he is to have all the hair cut off his head and his chin and over his eyes--all his hair is to be cut off--and he will have his clothing washed and his body bathed in water and he will be clean.

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

So changing his behaviour before them, he made it seem as if he was off his head, hammering on the doors of the town, and letting the water from his mouth go down his chin.

And Joab said to Amasa, Is it well, my brother? And with his right hand he took him by the hair of his chin to give him a kiss.

And hearing this, with signs of grief and pulling out the hair of my head and my chin, I took my seat on the earth deeply troubled.

And you, son of man, take a sharp sword, using it like a haircutter's blade, and making it go over your head and the hair of your chin: and take scales for separating the hair by weight.
