Tobit 4:12 (KJV)
Beware of all whoredom my son and chiefly take a wife of the seed of thy fathers and take not a strange woman to wife which is not of thy ather’s tribe for we are the children of the prophets Noe Abraham Isaac and Jacob remember my son that our fathers from the beginning even that they all married wives of their own kindred and were blessed in their children and their seed shall inherit the land
