'Murderer' in the Bible

You belong to your father the Devil, and you want to carry out the desires of your father. He was a murderer from the beginning and has never stood for truth, since there is no truth in him. Whenever he tells a lie, he speaks in character, because he is a liar and the father of lies.

You rejected the Holy and Righteous One and asked to have a murderer released to you,

When the people who lived there saw the snake hanging from his hand, they told one another, "This man must be a murderer! He may have escaped from the sea, but Justice won't let him live."

Of course, none of you should suffer for being a murderer, thief, criminal, or troublemaker.

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