Joshua 24:18-22

18And the LORD drove out before us all the nations, including the Amorites, who lived in the land. We too will serve the LORD, because he is our God.” 19Joshua said to the people, “You are not able to serve the LORD . He is a holy God; he is a jealous God. He will not forgive your rebellion and your sins.

20If you forsake the LORD and serve foreign gods, he will turn and bring disaster on you and make an end of you, after he has been good to you.”

21But the people said to Joshua, “No! We will serve the LORD .”

22Then Joshua said, “You are witnesses against yourselves that you have chosen to serve the LORD .” “Yes, we are witnesses,” they replied.
