Genesis 29:27-31

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.”

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

Laban also gave his female slave Bilhah to his daughter Rachel as her slave.

So Jacob had relations with Rachel also, and indeed he loved Rachel more than Leah, and he served with Laban for another seven years.

Now the Lord saw that Leah was unloved, and He opened her womb, but Rachel was unable to have children.
