'Beard' in the Bible

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

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