8 And if the Lord shall enlarge thy borders, as he sware to thy fathers, and the Lord shall give to thee all the land which he said he would give to thy fathers;
9 if thou shalt hearken to do all these commands, which I charge thee this day, to love the Lord thy God, to walk in all his ways continually; thou shalt add for thyself yet three cities to these three.
