Genesis 29:23-27

23Now in the evening he took his daughter Leah and brought her to him; and Jacob had relations with her.

24Laban also gave his female slave Zilpah to his daughter Leah as a slave.

25So it came about in the morning that, behold, it was Leah! And he said to Laban, “1What is this that you have done to me? Was it not for Rachel that I served with you? Why then have you 2deceived me?”

26But Laban said, “It is not 3the practice in our place to 4marry off the younger before the firstborn.

27Complete the week of this one, and we will give you the other also for the service which 5you shall serve with me, for another seven years.”
