'Canker worm' in the Bible

Sworn hath Jehovah of Hosts by Himself, That, Surely I have filled thee with men as the cankerworm, And they have cried against thee -- shouting.

Lift ye up an ensign in the land, Blow a trumpet among nations, Sanctify against it nations, Summon against it the kingdoms of Ararat, Minni, and Ashkenaz, Appoint against it an infant head, Cause the horse to ascend as the rough cankerworm.
