1 Samuel 7:3

And Samuel spake unto all the house of Israel, saying, with reference to the apparent sincere sorrow of the people, If ye do return unto the Lord with all your hearts, if their lamenting was no mere sham and hypocrisy, then put away the strange gods and Ashtaroth, the male and female idols of the heathen nations of Canaan, from among you, and prepare your hearts unto the Lord, firmly established in faith and trust in Him, and serve Him only, for the service of the true God and of false deities of any kind does not agree together; and He will deliver you out of the hand of the Philistines, announcing His relation as covenant God to them by saving them from their enemies and once more establishing them as an independent people.
