devour

Definition:

The term "devour" means to eat or consume in an aggressive manner.

Using this word in a figurative sense, Paul warned believers to not devour one another, meaning to not attack or destroy each other with words or actions (Galatians 5:15).
Also in a figurative sense, the term "devour" is often used with a meaning of "completely destroy" as when talking about nations devouring each other or a fire devouring buildings and people.
This term could also be translated as "completely consume" or "totally destroy."
