1 Samuel 7:3-6

3And Samuel spoke to all the house of Israel, saying, If ye return to Jehovah with all your heart, put away the strange 1gods and the Ashtoreths from among you, and apply your hearts unto Jehovah, and serve him only; and he will deliver you out of the hand of the Philistines.

4And the children of Israel put away the Baals and the Ashtoreths and served Jehovah only.

5And Samuel said, Gather all Israel to Mizpah, and I will pray Jehovah for you.

6And they gathered together to Mizpah, and drew water, and poured it out before Jehovah, and fasted on that day, and said there, We have sinned against Jehovah. And Samuel judged the children of Israel in Mizpah.
