Deuteronomy 27:24

Thou shalt not kill.

He that smiteth a man, so that he die, shall be surely put to death. And if a man lie not in wait, but God deliver him into his hand; then I will appoint thee a place whither he shall flee. But if a man come presumptuously upon his neighbor, to slay him with guile; thou shalt take him from mine altar, that he may die.

And he that killeth any man shall surely be put to death.

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.

But if any man hate his neighbor, and lie in wait for him, and rise up against him, and smite him mortally that he die, and fleeth into one of these cities:

And when Abner was returned to Hebron, Joab took him aside in the gate to speak with him quietly, and smote him there under the fifth rib, that he died, for the blood of Asahel his brother.

And he wrote in the letter, saying, Set ye Uriah in the forefront of the hottest battle, and retire ye from him, that he may be smitten, and die. And it came to pass, when Joab observed the city, that he assigned Uriah unto a place where he knew that valiant men were. And the men of the city went out, and fought with Joab: and there fell some of the people of the servants of David; and Uriah the Hittite died also.
