Genesis 29:23-27

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

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

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

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

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