2 Kings 6:24-25

But it came about after this, that Ben-hadad king of Aram (Syria) gathered his whole army together and went up and besieged Samaria. Now there was a great famine in Samaria; and they besieged it until a donkey’s head was sold for eighty shekels of silver, and a fourth of a kab of dove’s dung for five shekels of silver.
