Ibid., a town in Benjamin, not far from Jerusalem, towards the north (Isaiah 10:31). The same Hebrew word occurs in Isaiah 25:10, where it is rendered "dunghill." This verse has, however, been interpreted as meaning "that Moab will be trodden down by Jehovah as teben [broken straw] is trodden to fragments on the threshing-floors of Madmenah."
