1 Samuel 7:6-8

7:6 After they had assembled at Mizpah, they drew water and poured it out before the Lord. They fasted on that day, and they confessed there, “We have sinned against the Lord.” So Samuel led the people of Israel at Mizpah.

7:7 When the Philistines heard that the Israelites had gathered at Mizpah, the leaders of the Philistines went up against Israel. When the Israelites heard about this, they were afraid of the Philistines. 7:8 The Israelites said to Samuel, “Keep crying out to the Lord our God so that he may save us from the hand of the Philistines!”
