'Murderers' in the Bible

For the one who takes revenge against murderers took notice of the oppressed; he did not overlook their cry for help

Lord, use your power to deliver me from these murderers, from the murderers of this world! They enjoy prosperity; you overwhelm them with the riches they desire. They have many children, and leave their wealth to their offspring.

How long will you threaten a man? All of you are murderers, as dangerous as a leaning wall or an unstable fence.
