Genesis 29:22-30

So Laban brought together all the people of the place and gave a feast. But when evening came, he took his daughter Leah and brought her to Jacob, and Jacob made love to her. And Laban gave his servant Zilpah to his daughter as her attendant. When 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?” Laban replied, “It is not our custom here to give the younger daughter in marriage before the older one. Finish this daughter’s bridal week; then we will give you the younger one also, in return for another seven years of work.” And Jacob did so. He finished the week with Leah, and then Laban gave him his daughter Rachel to be his wife. Laban gave his servant Bilhah to his daughter Rachel as her attendant. Jacob 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.
