Joshua 23:11

9 The LORD has driven out great and powerful nations before you, and to this day no one can stand against you.

10 One of you can put a thousand to flight, because the LORD your God fights for you, just as He promised.

Therefore watch yourselves carefully, that you love the LORD your God.

12 For if you turn away and cling to the rest of these nations that remain among you, and if you intermarry and associate with them,

13 know for sure that the LORD your God will no longer drive out these nations before you. Instead, they will become for you a snare and a trap, a scourge in your sides and thorns in your eyes, until you perish from this good land that the LORD your God has given you.

Do read the surrounding verses too, because the context often says more than a single verse.
