'Murderers' in the Bible

Meanwhile, Elisha was sitting in his house, along with the elders, when the king sent a man to kill him, but before the messenger arrived, Elisha told the elders, "Are you watching how this descendant of murderers has ordered my head be cut off? Look, when the messenger arrives, shut the door and hold it to shut them out! Don't you hear the sound of his master's feet right behind him?"

But the children of the murderers he slew not: according unto that which is written in the book of the law of Moses, wherein the LORD commanded, saying, The fathers shall not be put to death for the children, nor the children be put to death for the fathers; but every man shall be put to death for his own sin.

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

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

How is the faithful city become an harlot! it was full of judgment; righteousness lodged in it; but now murderers.

For I have heard a voice as of a woman in travail, and the anguish as of her that bringeth forth her first child, the voice of the daughter of Zion, that bewaileth herself, that spreadeth her hands, saying, Woe is me now! for my soul is wearied because of murderers.
