Genesis 29:25-30
25 When morning came, there was Leah! So he said to Laban, “What is this you have done to me? Wasn’t it for Rachel that I worked for you? Why have you deceived me?”
26 Laban answered, “It is not the custom in this place to give the younger daughter in marriage before the firstborn.
27 Complete this week of wedding celebration, and we will also give you this younger one in return for working yet another seven years for me.”
28 And Jacob did just that. He finished the week of celebration, and Laban gave him his daughter Rachel as his wife.
29 And Laban gave his slave Bilhah to his daughter Rachel as her slave.
30 Jacob slept with Rachel also, and indeed, he loved Rachel more than Leah. And he worked for Laban another seven years.(A)
