'Beard' in the Bible

Then Mephibosheth the [grand]son of Saul came down to meet the king, but he had not cared for his feet, nor trimmed his mustache, nor washed his clothes from the day the king left until the day he returned in peace and safety.

Joab said to Amasa, “Is it going well with you, my brother?” And with his right hand Joab took hold of Amasa by the beard [as if] to kiss him [in greeting].
