12. Don't ever turn your backs on him by marrying people from the nations that are left in the land. Don't even make friends with them. I tell you that if you are friendly with those nations, the LORD won't chase them away when you attack. Instead, they'll be like a trap for your feet, a whip on your back, and thorns in your eyes. And finally, none of you will be left in this good land that the LORD has given you.
