Numbers 33:53-55 Modern English Version (MEV)
53 and you will drive out the inhabitants of the land and dwell in it, because I have given you the land to inherit it. 54 You will possess the land by lot for an inheritance among your families, and to the larger you will give the larger inheritance, and to the smaller you will give the smaller inheritance. Every man’s inheritance will be in the place where his lot falls. By the tribes of your fathers you will inherit.
55 But if you do not drive out the inhabitants of the land from before you, then those whom you let remain will be like thorns in your eyes and thorns in your sides. They will show hostility to you in the land in which you live.
