Israel's dismissive term for the miraculous manna God provided in the wilderness. The word combines contempt with ideas of lightness or worthlessness - not substantial, not satisfying, beneath their dignity. This stunning rejection of heaven's bread crystallizes Israel's chronic ingratitude. They called worthless what God called wonderful. The term reveals how sustained complaining warps perception until even miracles become occasions for resentment. Their 'worthless bread' was sustaining millions daily, but familiarity had bred contempt.
