'Killing' in the Bible

So when David returned from killing the Philistine, Abner took him and brought him before Saul with the Philistine’s head in his hand.

It happened as they were coming, when David returned from killing the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet King Saul, with tambourines, with joy and with musical instruments.

and they took captive the women and all who were in it, both small and great, without killing anyone, and carried them off and went their way.
