2 Samuel 10:4-5; 2 Samuel 20:9
Wherefore Hanun took David's servants, and shaved off the one half of their beards, and cut off their garments in the middle, even to their buttocks, and sent them away .
When they told it unto David, he sent to meet them, because the men were greatly ashamed : and the king said , Tarry at Jericho until your beards be grown , and then return .
And Joab said to Amasa, Art thou in health, my brother? And Joab took Amasa by the beard with the right hand to kiss him.
