'Murderer' in the Bible

Ye are of the devil, as your father, and ye desire to do the lusts of your father. He was a murderer from the beginning, and has not stood in the truth, because there is no truth in him. When he speaks falsehood, he speaks of what is his own; for he is a liar and its father:

But ye denied the holy and righteous one, and asked that a man that was a murderer should be granted to you;

And when the barbarians saw the beast hanging from his hand, they said to one another, This man is certainly a murderer, whom, though saved out of the sea, Nemesis has not allowed to live.

Let none of you suffer indeed as murderer, or thief, or evildoer, or as overseer of other people's matters;

Every one that hates his brother is a murderer, and ye know that no murderer has eternal life abiding in him.
