36:3 And if they be married to any of the sons of the [other] tribes of the children of Israel, then shall their inheritance be taken from the inheritance of our fathers, and shall be put to the inheritance of the tribe whereunto they are received: so shall it be taken from the lot of our inheritance. King of kings' Bible - Numbers
7:1 When the "I AM" thy God shall bring thee into the land where thou goest to possess it, and hath cast out many nations before thee, the Hittites, and the Girgashites, and the Amorites, and the Canaanites, and the Perizzites, and the Hivites, and the Jebusites, seven nations greater and mightier than thou;
7:2 And when the "I AM" thy God shall deliver them before thee; thou shalt smite them, [and] utterly destroy them; thou shalt make no covenant with them, nor show mercy unto them:
7:3 Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.
7:4 For they will turn away thy son from following Me, that they may serve other gods: so will the anger of the "I AM" be kindled against you, and destroy thee suddenly. King of kings' Bible - Deuteronomy
