Numbers 33:54-56

Revised Standard Version

⁵⁴ You shall inherit the land by lot according to your families; to a large tribe you shall give a large inheritance, and to a small tribe you shall give a small inheritance; wherever the lot falls to any man, that shall be his; according to the tribes of your fathers you shall inherit. ⁵⁵ But if you do not drive out the inhabitants of the land from before you, then those of them whom you let remain shall be as pricks in your eyes and thorns in your sides, and they shall trouble you in the land where you dwell. ⁵⁶ And I will do to you as I thought to do to them.”
