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.
KJV
But if ye will not drive out the inhabitants of the land from before you; then it shall come to pass, that those which ye let remain of them [shall be] pricks in your eyes, and thorns in your sides, and shall vex you in the land wherein ye dwell.
ASV
But if ye will not drive out the inhabitants of the land from before you, then shall those that ye let remain of them be as pricks in your eyes, and as thorns in your sides, and they shall vex you in the land wherein ye dwell.
