'Slaughter' in the Bible

Now it came to pass after the death of Saul, when David was returned from the slaughter of the Amalekites, and David had abode two days in Ziklag;

Behold, he is hid now in some pit, or in some other place: and it will come to pass, when some of them be overthrown at the first, that whosoever heareth it will say, There is a slaughter among the people that follow Absalom.

Where the people of Israel were slain before the servants of David, and there was there a great slaughter that day of twenty thousand men.
