'Heads' in the Bible

(Yod) The elders of Daughter Zion sit on the ground in silence. They have thrown dirt on their heads; They have dressed in sackcloth. Jerusalem's young women stare down at the ground.

(Samek) All who passed by on the road clapped their hands to mock you. They sneered and shook their heads at Daughter Jerusalem. "Ha! Is this the city they called 'The perfection of beauty, the source of joy of the whole earth!'?"
