'Beard' in the Bible

And Mephibosheth the son of Saul came down to meet the king; and he had neither dressed his feet, nor trimmed his beard, nor washed his clothes, from the day the king departed until the day he came home in peace.

And Joab said to Amasa, Is it well with thee, my brother? And Joab took Amasa by the beard with his right hand to kiss him.
