Tobit 4:12

Revised Standard Version

¹² “Beware, my son, of all immorality. First of all take a wife from among the descendants of your fathers and do not marry a foreign woman, who is not of your father’s tribe; for we are the sons of the prophets. Remember, my son, that Noah, Abraham, Isaac, and Jacob, our fathers of old, all took wives from among their brethren. They were blessed in their children, and their posterity will inherit the land.
