“Beware, my son, of every kind of fornication. First of all, marry a woman from among the descendants of your ancestors; do not marry a foreign woman, who is not of your father’s tribe; for we are the descendants of the prophets. Remember, my son, that Noah, Abraham, Isaac, and Jacob, our ancestors of old, all took wives from among their kindred. They were blessed in their children, and their posterity will inherit the land.
