What does Joshua 23:12 mean?

Know for sure that the Lord your God will stop driving out these nations for you. They’ll become traps and snares for you, whips on your backs and thorns in your eyes, until you disappear from this good land the Lord your God has given you. Joshua 23:12 - Modern Text Bible

(He warns that if they turn away from God, the nations will become a source of pain and trouble, and they’ll lose the land.)
