'Slaughter' in the Bible

So [the] Philistines fought and Israel was defeated and each man fled to his tent, for the slaughter was very great. Thirty thousand foot soldiers from Israel fell.

Then Saul said, "Disperse [yourselves] among the troops and say to them, 'Bring to me each [one] his ox and each his sheep and slaughter them in this [place] and eat, but do not sin against Yahweh by eating [the animals] with the blood.'" So all the troops brought [them], each [leading] his ox in his hand that night, and slaughtered [it] there.
