Joshua 24:20-24

If you forsake the LORD and serve foreign gods, then He will turn and do you harm and consume you after He has done good to you.” The people said to Joshua, “No, but we will serve the LORD.” Joshua 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 therefore, put away the foreign gods which are in your midst, and incline your hearts to the LORD, the God of Israel.” The people said to Joshua, “We will serve the LORD our God and we will obey His voice.”
