'Gnaw' in the Bible

“They are gaunt with want and famine;They gnaw the dry and barren ground by night in [the gloom of] waste and desolation.

“My bones are pierced [with aching] in the night season,And the pains that gnaw me take no rest.

‘You will drink it and drain it,Then you will gnaw its fragmentsAnd tear your breasts;for I have spoken,’ says the Lord God.

Her officials within her are roaring lions;Her judges are [as hungry as] the wolves at evening,They leave nothing for the morning.
