Genesis 29:20-27

So Jacob served Laban for seven years in exchange for Rachel, but because he loved her so deeply, the seven years seemed like only a few days. After the seven years, Jacob said to Laban, “My time is fulfilled; give me your daughter so that I may marry her and sleep with her.” So Laban prepared a wedding feast and invited all the people of the surrounding area. That night, Laban tricked Jacob by bringing his older daughter Leah to Jacob’s tent, and he slept with her on his wedding night! (Laban assigned Zilpah to be Leah’s servant.) When Jacob woke up the next morning, he was shocked to find Leah lying next to him! So he confronted Laban and said, “What have you done to me? Didn’t I serve you these seven years for Rachel? Why have you tricked me?” Laban answered, “It’s not our custom here to give the younger daughter in marriage before the older daughter is married. Wait until this bridal week of festivities is over, then I’ll give you Rachel, but you must serve me for another seven years.”
