'Murderer' in the Bible

You are of your father the devil, and it is your will to practice the desires [which are characteristic] of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. When he lies, he speaks what is natural to him, for he is a liar and the father of lies and half-truths.

But you disowned and denied the Holy and Righteous One and asked for [the pardon of] 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 [the avenging goddess] has not permitted him to live.”

Make sure that none of you suffers as a murderer, or a thief, or any sort of criminal [in response to persecution], or as a troublesome meddler interfering in the affairs of others;

Everyone who hates (works against) his brother [in Christ] is [at heart] a murderer [by God’s standards]; and you know that no murderer has eternal life abiding in him.
