'Murderer' in the Bible

‘But if he struck his victim down [intentionally] with an iron object so that he died, he is a murderer; the murderer shall certainly be put to death.

If he struck his victim down [intentionally] with a stone in hand, which may cause a person to die, and he died, he is a murderer; the murderer shall certainly be put to death.

Or if he struck his victim down [intentionally] with a wooden object in hand, which may cause a person to die, and he died, he is a murderer; the murderer shall certainly be put to death.

The blood avenger shall himself put the murderer to death; he shall put him to death when he meets him.

or if, in enmity, he struck the victim down with his hand, and he died, the one that struck the victim shall certainly be put to death; he is a murderer. The blood avenger shall put the murderer to death when he meets him.

‘If anyone kills a person [intentionally], the murderer shall be put to death on the testimony of [two or more] witnesses; but no one shall be put to death on the testimony of [only] one witness.

Moreover, you shall not accept a ransom [in exchange] for the life of a murderer guilty and sentenced to death; but he shall certainly be put to death.
