'Kill' in the Bible

Then the king of Israel said to Elisha when he saw them, "Shall I kill them? Shall I kill, my father?"

And he said, "You shall not kill. Would you kill [those] whom you took captive with the sword or with the bow? Put food and water before them that they may eat and drink and then go to their master."

If we say, 'Let us go [into] the city,' the famine [is] in the city, and we shall die there; but if we sit here, we shall die. So then, come, let us fall into the camp of [the] Arameans. If they let us live, we shall live; but if they kill us, then we shall die."

Then Hazael asked, "Why [is] my lord crying?" He said, "Because I know what evil you will do to the {Israelites}. You will {set their fortifications on fire}, and you will kill their young men with the sword. Their little ones you will dash to pieces, and their pregnant women you will rip open!"

It happened that when he finished offering the burnt offering, Jehu said to the royal guard and to the officers, "Come and kill them; let no man go free!" So {they put them to the sword}, and the royal guard and the officers threw them out, then they went up to the citadel of the temple of Baal.

Then Jehoiada the priest commanded the commanders of the hundreds, the appointed of the army, and he said to them, "Bring her out to the house of the ranks! The one coming after her [should] kill her with the sword," for the priest had said, "Let her not be killed in the temple of Yahweh."

But the sons of the killers he did not kill, as it is written in the scroll of the law of Moses which Yahweh had commanded, saying, "Fathers should not be killed because of children, and children should not be killed because of fathers; but a man should die because of his [own] sin."
