Genesis 29:23-30

23But when evening came, he took his daughter Leah and brought her to Jacob, and Jacob made love to her.

24And Laban gave his servant Zilpah to his daughter as her attendant.

25When morning came, there was Leah! So Jacob said to Laban, “What is this you have done to me? I served you for Rachel, didn’t I? Why have you deceived me?” 26Laban replied, “It is not our custom here to give the younger daughter in marriage before the older one.

27Finish this daughter’s bridal week; then we will give you the younger one also, in return for another seven years of work.” 28And Jacob did so. He finished the week with Leah, and then Laban gave him his daughter Rachel to be his wife. 29Laban gave his servant Bilhah to his daughter Rachel as her attendant.

30Jacob made love to Rachel also, and his love for Rachel was greater than his love for Leah. And he worked for Laban another seven years.
