1 Samuel 7:1-6

And the men of Kiriath-jearim came, and fetched up the ark of Jehovah, and brought it into the house of Abinadab in the hill, and sanctified Eleazar his son to keep the ark of Jehovah. And it came to pass, from the day that the ark abode in Kiriath-jearim, that the time was long; for it was twenty years: and all the house of Israel lamented after Jehovah. And Samuel spake unto all the house of Israel, saying, If ye do return unto Jehovah with all your heart, then put away the foreign gods and the Ashtaroth from among you, and direct your hearts unto Jehovah, and serve him only; and he will deliver you out of the hand of the Philistines. Then the children of Israel did put away the Baalim and the Ashtaroth, and served Jehovah only. And Samuel said, Gather all Israel to Mizpah, and I will pray for you unto Jehovah. And 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.
