Joshua 24:20-24

If you leave the LORD and serve other gods, he will send you great trouble. The LORD may have been good to you, but if you turn against him, he will destroy you.” But the people said to Joshua, “No! We will serve the LORD.” Then Joshua said, “You are your own witnesses that you have chosen to serve the LORD.” The people said, “Yes, we are.” Then Joshua said, “Now throw away the gods that you have. Love the LORD, the God of Israel, with all your heart.” Then the people said to Joshua, “We will serve the LORD our God, and we will obey him.”
