This Hebrew word, untranslated, denotes a round vessel used as a measure both for liquids and solids. It was equal to one homer, and contained ten ephahs in dry and ten baths in liquid measure (Ezekiel 45:14). The Rabbins estimated the cor at forty-five gallons, while Josephus estimated it at about eighty-seven. In 1 Kings 4:22; 5:11; 2Chr 2:10; 27:5, the original word is rendered "measure."
