Tobit 4:12

12 “Beware, my son, of every kind of sexual immorality. 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 prophets and true-born sons of prophets. The first prophet wasc Abraham, then Isaac and Jacob, our ancestors of old. Remember, my son, that these all took wives from among their kindred. They were blessed in their children, and their posterity will inherit the land.*
