1 Samuel 7:3-6

3Then Samuel spoke to all the house of Israel, saying, “If you return to the Lord with all your hearts, then put away the foreign gods and the Ashtoreths from among you, and prepare your hearts for the Lord, and serve Him only; and He will deliver you from the hand of the Philistines.”

4So the children of Israel put away the Baals and the Ashtoreths, and served the Lord only.

5And Samuel said, “Gather all Israel to Mizpah, and I will pray to the Lord for you.”

6So they gathered together at Mizpah, drew water, and poured it out before the Lord. And they fasted that day, and said there, “We have sinned against the Lord.” And Samuel judged the children of Israel at Mizpah.
