1 Samuel 7:1-5

And the men of Kiriath-jearim came and took the ark of the Lord and brought it into the house of Abinadab on the hill, and they consecrated his son Eleazar to watch over the ark of the Lord.

From the day that the ark remained at Kiriath-jearim, the time was long, for it was twenty years; and all the house of Israel mourned after the Lord.

Then Samuel spoke to all the house of Israel, saying, “If you are returning to the Lord with all your heart, then remove the foreign gods and the Ashtaroth from among you, and direct your hearts to the Lord and serve Him alone; and He will save you from the hand of the Philistines.”

So the sons of Israel removed the Baals and the Ashtaroth, and served the Lord alone.

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