CORUS, OMER, HOMER, or CHOMER, in the Jewish antiquities, a measure containing 10 baths or 75 gallons and five pints, as a measure of things liquid, and 32 pecks and 1 pint as a measure for things dry. The corus or omer was most commonly a measure for things dry; and the greatest that was used among the Jews. It contained, according to the rabbins, 10 ephahs or 30 sata or seahs. Corus is the most usual term in the historical writers, and omer or chomer among the prophets.
