And it came to pass, while the ark abode in Kirjathjearim, that the time was long; for it was twenty years: and all the house of Israel lamented after the LORD. 1 Samuel 7.2So Samuel told them what to do. Get rid of all their other gods and worship Yahweh alone. So the Israelites rounded up all their gods and threw them away. When the Philistines heard about all this, they prepared to attack Israel.
The Israelites asked Samuel to ask God to save them. So Samuel killed a baby lamb and burned its dead body for God. Then Samuel cried out to God and God heard him.
Samuel took a sucking lamb, and offered it for a burnt offering wholly unto the LORD: and Samuel cried unto the LORD for Israel; and the LORD heard him. 7.9While Samuel was busy roasting the lamb for God, the Philistines attacked. And God "thundered with a great thunder" and "discomfited them." Then the Israelites chased them down and killed them.
As Samuel was offering up the burnt offering, the Philistines drew near to battle against Israel: but the LORD thundered with a great thunder on that day upon the Philistines, and discomfited them; and they were smitten before Israel. And the men of Israel went out of Mizpeh, and pursued the Philistines, and smote them. 7.10-11After the slaughter, Samuel put up a monument that said, "So far the Lord has helped us."
Hitherto hath the LORD helped us. 7.12Once again the Bible doesn't say how many Philistines were killed. So I'll just call it 1000.
