'Canker worm' in the Bible

Jehovah of hosts hath sworn by himself,'saying , Surely I will fill thee with men, as with the canker-worm; and they shall lift up a shout against thee.

Set ye up a standard in the land, blow the trumpet among the nations, prepare the nations against her, call together against her the kingdoms of Ararat, Minni, and Ashkenaz: appoint a marshal against her; cause the horses to come up as the rough canker-worm.
