If you don't force out all the people there, they will be like pointed sticks in your eyes and thorns in your back. They will always be trouble for you,
When that happens, the people of Israel will no longer have cruel neighbours that abuse them and make them feel as though they are in a field of thorns and briers. And the Israelites will know that I, the LORD God, have done these things.
Of course, I am now referring to the wonderful things I saw. One of Satan's angels was sent to make me suffer terribly, so that I would not feel too proud.
If you do, those people will lead your descendants to worship other gods and to turn their backs on the LORD. That will make him very angry, and he will quickly destroy Israel.
Don't have anything to do with the nations that live around you. Don't worship their gods or pray to their idols or make promises in the names of their gods.
