Joshua 24:18-24

And the LORD drove out before us all the peoples, the Amorites who lived in the land. Therefore we also will serve the LORD, for he is our God.” But Joshua said to the people, “You are not able to serve the LORD, for he is a holy God. He is a jealous God; he will not forgive your transgressions or your sins. If you forsake the LORD and serve foreign gods, then he will turn and do you harm and consume you, after having done you good.” And the people said to Joshua, “No, but we will serve the LORD.” Then Joshua said to the people, “You are witnesses against yourselves that you have chosen the LORD, to serve him.” And they said, “We are witnesses.” He said, “Then put away the foreign gods that are among you, and incline your heart to the LORD, the God of Israel.” And the people said to Joshua, “The LORD our God we will serve, and his voice we will obey.”
