Numbers 33:55-56

New Revised Standard Version, Anglicised Catholic Edition

⁵⁵ But if you do not drive out the inhabitants of the land from before you, then those whom you let remain shall be as barbs in your eyes and thorns in your sides; they shall trouble you in the land where you are settling. ⁵⁶ And I will do to you as I thought to do to them.
