'Murderer' in the Bible

The father whose sons you are is the Devil; and you desire to do what gives him pleasure. *He* was a murderer from the beginning, and does not stand firm in the truth--for there is no truth in him. Whenever he utters his lie, he utters it out of his own store; for he is a liar, and the father of lies.

Every one who hates his brother man is a murderer; and you know that no murderer has the Life of the Ages continuing in him.
