throw to the wolves
Also, throw to the dogs or lions . Send to a terrible fate; sacrifice someone, especially so as to save oneself. For example, Leaving him with hostile reporters was throwing him to the wolves, or If Bob doesn't perform as they expect, they'll throw him to the lions. All three hyperbolic terms allude to the ravenous appetite of these animals, which presumably will devour the victim. The first term comes from Aesop's fable about a nurse who threatens to throw her charge to the wolves if the child does not behave. [First half of 1900s]
