'Murderer' in the Bible

Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode 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 of it.

But ye denied the Holy One and the Just, and desired a murderer to be granted unto you;

And when the barbarians saw the venomous beast hang on his hand, they said among themselves, No doubt this man is a murderer, whom, though he hath escaped the sea, yet vengeance suffereth not to live.

But let none of you suffer as a murderer, or as a thief, or as an evildoer, or as a busybody in other men's matters.

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