'Murderer' in the Bible

You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.

But you disowned the Holy and Righteous One and asked for a murderer to be granted to you,

When the natives saw the creature hanging from his hand, they began saying to one another, “Undoubtedly this man is a murderer, and though he has been saved from the sea, justice has not allowed him to live.”

Make sure that none of you suffers as a murderer, or thief, or evildoer, or a troublesome meddler;

Everyone who hates his brother is a murderer; and you know that no murderer has eternal life abiding in him.
