Genesis 29:20-27
English Standard Version
21Then Jacob said to Laban, "Give me my wife that I may go in to her, for my time is completed."
22So Laban gathered together all the people of the place and made a feast.
23But in the evening he took his daughter Leah and brought her to Jacob, and he went in to her.
24(Laban gave his female servant Zilpah to his daughter Leah to be her servant.)
25And in the morning, behold, it was Leah! And Jacob said to Laban, "What is this you have done to me? Did I not serve with you for Rachel? Why then have you deceived me?"
26Laban said, "It is not so done in our country, to give the younger before the firstborn.
27Complete the week of this one, and we will give you the other also in return for serving me another seven years."
