12 “Be on your guard, son, against every kind of fornication, and above all, marry a woman of your own ancestral family. Do not marry a foreign woman, one who is not of your father’s tribe, because we are descendants of the prophets, who were the first to speak the truth. Noah prophesied first, then Abraham, Isaac, and Jacob, our ancestors from the beginning of time. Son, remember that all of them took wives from among their own kindred and were blessed in their children, and that their posterity would inherit the land.
