'Murderer' in the Bible

And if he smite him with an instrument of iron, so that he die, he is a murderer: the murderer shall surely be put to death.

And if he smite him with throwing a stone, wherewith he may die, and he die, he is a murderer: the murderer shall surely be put to death.

Or if he smite him with an hand weapon of wood, wherewith he may die, and he die, he is a murderer: the murderer shall surely be put to death.

The revenger of blood himself shall slay the murderer: when he meeteth him, he shall slay him.

Or in enmity smite him with his hand, that he die: he that smote him shall surely be put to death; for he is a murderer: the revenger of blood shall slay the murderer, when he meeteth him.

Whoso killeth any person, the murderer shall be put to death by the mouth of witnesses: but one witness shall not testify against any person to cause him to die.

Moreover ye shall take no satisfaction for the life of a murderer, which is guilty of death: but he shall be surely put to death.
