"Three Leahs to get one Rachel"
In the Book of Genesis, Jacob wishes to marry Rachel. He asks permission from her father, Laban, who gives his consent after Jacob has worked for him for seven years. However Laban is anxious to marry off his older, less attractive daughter Leah first. He tricks Jacob by dressing Leah in a thick veil so that he marries her without realising who she is. When Jacob discovers what has happened, Laban promises to let him marry Rachel if he will stay and work for him for another seven years.
