'Murderer' in the Bible

"But if he hits someone with an iron tool so that he dies, he is a murderer. The murderer must surely be put to death.

If he strikes him by throwing a stone large enough that he could die, and he dies, he is a murderer. The murderer must surely be put to death.

Or if he strikes him with a wooden hand weapon so that he could die, and he dies, he is a murderer. The murderer must surely be put to death.

The avenger of blood himself must kill the murderer; when he meets him, he must kill him.

or with enmity he strikes him with his hand and he dies, the one who struck him must surely be put to death, for he is a murderer. The avenger of blood must kill the murderer when he meets him.

"Whoever kills any person, the murderer must be put to death by the testimony of witnesses; but one witness cannot testify against any person to cause him to be put to death.

Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death.

When Jehu came through the gate, she said, "Is everything all right, Zimri, murderer of his master?"

Before daybreak the murderer rises up; he kills the poor and the needy; in the night he is like a thief.

I will punish you as an adulteress and murderer deserves. I will avenge your bloody deeds with furious rage.
