'Killing' in the Bible

All the people and all Israel realized on that day that the killing of Abner son of Ner was not done at the king's instigation.

But Abishai the son of Zeruiah came to David's aid, striking the Philistine down and killing him. Then David's men took an oath saying, "You will not go out to battle with us again! You must not extinguish the lamp of Israel!"

When the angel extended his hand to destroy Jerusalem, the Lord relented from his judgment. He told the angel who was killing the people, "That's enough! Stop now!" (Now the Lord's angel was near the threshing floor of Araunah the Jebusite.)
