'Hair' in the Bible

The next day, a man escaped from Saul's camp! With torn clothes and dirty hair, he approached David, fell to the ground, and bowed down to him.

So Hanun took David's servants, and after cutting off half the hair on their chins, and cutting off the skirts of their robes up to the middle, he sent them away.

When David had news of it, he sent men out with the purpose of meeting them on their way, for the men were greatly shamed: and the king said, Go to Jericho till your hair is long again, and then come back.

Then said she, I pray thee, let the king remember the LORD thy God, that thou wouldest not suffer the revengers of blood to destroy any more, lest they destroy my son. And he said, As the LORD liveth, there shall not one hair of thy son fall to the earth.

And when he polled his head, (for it was at every year's end that he polled it: because the hair was heavy on him, therefore he polled it:) he weighed the hair of his head at two hundred shekels after the king's weight.

And Mephibosheth, the son of Saul's son, came down for the purpose of meeting the king; his feet had not been cared for or his hair cut or his clothing washed from the day when the king went away till the day when he came back in peace.

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.
