'Slaughter' in the Bible

So the Philistines fought; Israel was defeated and every man fled to his tent. It was a very great defeat, for thirty thousand foot soldiers of Israel fell.

The messenger replied, “Israel has fled before the Philistines and there has also been a great slaughter among the people. Also your two sons, Hophni and Phinehas, are dead, and the ark of God has been taken.”

The Lord struck down some of the men of Beth-shemesh because they had looked into the ark of the Lord. He struck down 50,070 men among the people, and the people mourned because the Lord had struck the people with a great slaughter.

That first slaughter which Jonathan and his armor bearer made was about twenty men within about half a [plow] furrow in a plot of land [the area of which a yoke of oxen could plow in a day].

How much better [it would have been] if only the people had eaten freely today from the spoil of their enemies which they found! For now the slaughter among the Philistines has not been great.”

Then there was war again, and David went out and fought with the Philistines and defeated them with a great slaughter, and they fled before him.

So David and his men went to Keilah and fought the Philistines; he drove away their cattle and struck them with a great slaughter. So David rescued the inhabitants of Keilah.
