Genesis 29:22-30

So Laban invited everyone in the neighborhood and prepared a wedding feast. But that night, when it was dark, Laban took Leah to Jacob, and he slept with her. (Laban had given Leah a servant, Zilpah, to be her maid.) But when Jacob woke up in the morning—it was Leah! “What have you done to me?” Jacob raged at Laban. “I worked seven years for Rachel! Why have you tricked me?” “It’s not our custom here to marry off a younger daughter ahead of the firstborn,” Laban replied. “But wait until the bridal week is over; then we’ll give you Rachel, too—provided you promise to work another seven years for me.” So Jacob agreed to work seven more years. A week after Jacob had married Leah, Laban gave him Rachel, too. (Laban gave Rachel a servant, Bilhah, to be her maid.) So Jacob slept with Rachel, too, and he loved her much more than Leah. He then stayed and worked for Laban the additional seven years.
