'Murderer' in the Bible

Ye are of your father the devil, and the lusts of your father it is your will to do. He was a murderer from the beginning, and standeth not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father thereof.

But ye denied the Holy and Righteous One, and asked for a murderer to be granted unto you,

And when the barbarians saw the venomous creature hanging from his hand, they said one to another, No doubt this man is a murderer, whom, though he hath escaped from the sea, yet Justice hath not suffered to live.

For let none of you suffer as a murderer, or a thief, or an evil-doer, or as a meddler in other men's matters:

Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
