Joshua 23:15-16

15The Lord has given to you every good thing that he has promised. But if you refuse to obey him, he will also punish you in every way that he has promised. He will destroy you so that you no longer live in this good land that he has given to you.

16You must obey the rules that he commanded you to obey in his covenant. You must not serve or worship other gods. If you turn against him, the Lord your God will be very angry with you. Then very soon none of you will remain in this good land that he has given to you.’
