Genesis 29:26-30 New American Standard Bible (NASB)

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

27. 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."

28. Jacob did so and completed her week, and he gave him his daughter Rachel as his wife.

29. Laban also gave his maid Bilhah to his daughter Rachel as her maid.

30. So Jacob went in to Rachel also, and indeed he loved Rachel more than Leah, and he served with Laban for another seven years.
