'Killing' in the Bible

When Jehoram had established himself over his father’s kingdom, he strengthened his position by killing with the sword all his brothers as well as some of the princes of Israel.

Meanwhile, the troops that Amaziah had sent home from the battle raided the cities of Judah from Samaria to Beth-horon, killing 3,000 people and taking a large amount of war booty.

And it happened [that] after Amaziah came [back] from killing the Edomites, he brought the gods of the sons of Seir, and he stood them up to himself as gods and bowed down before them and make smoke offerings for them.

For there were many in the congregation that were not sanctified: therefore the Levites had the charge of the killing of the passovers for every one that was not clean, to sanctify them unto the LORD.
