'Slaughter' in the Bible

Now it came about after the death of Saul, when David had returned from the slaughter of the Amalekites, that David remained two days in Ziklag.

Behold, he has now hidden himself in one of the caves or in another place; and it will be when he falls on them at the first attack, that whoever hears it will say, ‘There has been a slaughter among the people who follow Absalom.’

The people of Israel were defeated there before the servants of David, and the slaughter there that day was great, 20,000 men.
