Genesis 29:27-30

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.
