Genesis 29:23-27

23But that night, when it was dark, Laban took Leah to Jacob, and he slept with her.

24(Laban had given Leah a servant, Zilpah, to be her maid.)

25But 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?”

26“It’s not our custom here to marry off a younger daughter ahead of the firstborn,” Laban replied.

27“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.”
