1 Samuel 7:5-6

5Then Samuel told all the Israelites, ‘Meet together at Mizpah. I will pray to the Lord for you there.’

6So they all met together at Mizpah. They got water from a well and they poured it out for the Lord. They did not eat food that day. They prayed and they said, ‘We have done bad things against the Lord.’ Samuel became leader of the Israelite people at Mizpah.
