4:12 "Be on your guard, son, against every form of immorality, and above all, marry a woman of the lineage of your forefathers. Do not marry a stranger who is not of your father’s tribe, because we are sons of the prophets. My boy, keep in mind Noah, Abraham, Isaac, and Jacob, our fathers from of old: all of them took wives from among their own kinsmen and were blessed in their children. Remember that their posterity shall inherit the land.
