Dove's dung is named as a food eaten during a famine in Samaria in 2 Kings 6:25. The narrative describes how, during the siege of Samaria by Syrian king Ben-Hadad, a quarter of a kab of 'dove's dung' was sold for five shekels of silver.
There has been considerable debate about what these words actually refer to. English Bible translations have varied, with the King James Version and the English Standard Version retaining the phrase 'dove's dung', whereas the New International Version reads 'seed pods' and the New Jerusalem Bible 'wild onions', for example.
The Geneva Bible posits that the dung was used as a fuel for fire. Jewish historian Josephus suggested that dove's dung could have been used as a salt substitute. An alternative view is that 'dove's dung' was a popular name for some other food, such as Star-of-Bethlehem or falafel. A third position, based on amending the Hebrew text, is that the passage actually refers to locust-beans, the fruit of the carob tree.
