Numbers 33:54-56

New Revised Standard Version Catholic Edition

⁵⁴ You shall apportion the land by lot according to your clans; to a large one you shall give a large inheritance, and to a small one you shall give a small inheritance; the inheritance shall belong to the person on whom the lot falls; according to your ancestral tribes you shall inherit. 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.
