'Ravening' in the Bible

They gape upon me with their mouth, as a ravening and a roaring lion.

There is a conspiracy of her prophets in the midst of her like a roaring lion ravening the prey; they devour souls; they take away treasure and precious things; they increase her widows in the midst of her;

Her princes in the midst of her are like wolves ravening the prey, to shed blood, to destroy souls, to get dishonest gain.

But beware of false prophets, which come to you in sheep's clothing, but within are ravening wolves.
