1 Samuel 7:6-9

6So they gathered together at Mizpah, drew water and poured it out before Adonai. They fasted on that day and said there, “We have sinned against Adonai.” Then Samuel was judging Bnei-Yisrael at Mizpah.

7Now when the Philistines heard that Bnei-Yisrael had assembled at Mizpah, the lords of the Philistines marched against Israel. When Bnei-Yisrael heard it, they were afraid of the Philistines.

8So Bnei-Yisrael said to Samuel, “Don’t stop crying out to Adonai our God for us, so He may save us from the hand of the Philistines!”

9Samuel took a nursing lamb and offered it as a whole burnt offering to Adonai. Then Samuel cried out to Adonai for Israel and Adonai answered him.
