'Murderers' in the Bible

How is the faithful city become a harlot! It was full of judgment; righteousness used to lodge in it, but now murderers.

For I hear a voice, as of a woman in travail, anguish as of her that bringeth forth her first child, the voice of the daughter of Zion: she moaneth, she spreadeth forth her hands, saying, Woe unto me! for my soul faileth because of murderers.
