Joshua 24:20-24

If you do abandon (reject) the LORD and serve foreign gods, then He will turn and do you harm and consume and destroy you after He has done you good.” The people said to Joshua, “No, but we will serve [only] the LORD.” Joshua then said to the people, “You are witnesses against yourselves that you have chosen for yourselves the LORD, to serve Him.” And they said, “We are witnesses.” “Now then, remove the foreign gods which are among you, and incline your hearts toward the LORD, the God of Israel.” The people said to Joshua, “We will serve the LORD our God and we will listen to and obey His voice.”
