But if you do not drive out the inhabitants of the land before you, those you allow to remain will become barbs in your eyes and thorns in your sides; they will harass you in the land where you settle.

…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.
